Quality is the foundation of an enterprise, while customer needs drive its evolution. In the realm of precision seal manufacturing, quality is not a destination but a process of continuous refinement. Doit Rubber Products Co., Ltd. (international brand: DoitRubber) has remained steadfast in its commitment to centering operations on actual customer application scenarios and honing product quality against rigorous standards. From precisely addressing customer requirements to implementing technical optimizations and upgrades, DoitRubber demonstrates — through tangible quality innovations — its founding philosophy of combining craftsmanship with a symbiotic relationship with its customers.       Back in April, during a visit by DoitRubber, the client identified a specific need to optimize the inspection process for Y-ring seals, based on the real-world application requirements of their oral care equipment. As critical sealing components, these Y-rings operate under complex conditions — characterized by reciprocating motion, fluctuating pressures, and high-frequency usage. Consequently, their sealing stability and product consistency directly impact the end-user experience and the equipment’s service life, placing extremely high demands on product reliability.   Given these rigorous dynamic operating conditions, the client — while already satisfied with the quality of DoitRubber’s existing products — sought to further enhance inspection precision and product consistency. Their goal was to eliminate the risk of hidden defects and effectively reduce manual re-inspection costs, thereby achieving a dual upgrade in both quality and efficiency. Every request from a client serves as a vital guide for DoitRubber to refine its quality standards; faced with these specialized, application-specific requirements, DoitRubber did not simply adhere to existing benchmarks but immediately initiated an internal, dedicated review process.       Leveraging years of deep expertise in precision rubber product manufacturing, the technical team thoroughly analyzed the core characteristics of dynamic sealing for Y-rings and pinpointed critical quality challenges. Traditional static AOI (Automated Optical Inspection) methods are limited to detecting surface flaws in a stationary state; they fail to simulate actual operating conditions, making it difficult to identify hidden issues — such as latent cracks or sealing instability — that only manifest during dynamic use. Having identified the root cause, DoitRubber rapidly finalized an optimization plan and decisively upgraded its equipment by implementing a dynamic compression inspection system, thereby breaking through the limitations of static inspection.   On July 9, a client visited the DoitRubber facility to tour the dynamic inspection production line and witness the end-to-end inspection process for Y-rings firsthand. The new dynamic compression inspection equipment simulates the compression and reciprocating motion experienced by the products during actual operation. After undergoing compression testing, the products move via conveyor belt into a multi-probe intelligent inspection zone. A monitor displays real-time, comprehensive inspection data, capturing hidden damage and minute defects that static inspection methods miss. This ensures a thorough, 360-degree screening for flaws and prevents defective products from leaving the facility. Compared to traditional methods, this dynamic compression inspection process aligns with real-world application scenarios, effectively verifying the product’s core sealing performance under dynamic operating conditions.       In the precision seal manufacturing sector, meeting basic specifications is merely the starting point; DoitRubber’s pursuit of quality lies in ensuring perfect application fit and exceeding expectations. Rejecting the conventional mindset that prioritizes production volume over application suitability, DoitRubber consistently centers its approach on the customer’s specific operating environment. We are uncompromising in our pursuit of excellence, embedding rigorous quality control across the entire product lifecycle — from design and manufacturing to final inspection. We go beyond merely satisfying industry standards, proactively aligning our products with the complex operating conditions of end-user equipment and unique customer requirements. Through continuous technological innovation, process refinement, and equipment upgrades, we actively address quality limitations and push the boundaries of performance excellence.       From listening to customer needs and proactively reviewing and optimizing processes to implementing technological innovations and delivering results that exceed quality expectations, this testing upgrade and customer follow-up exemplify DoitRubber’s core philosophy: “Customer First, Quality Foremost.” DoitRubber consistently places customer needs at the heart of its innovation, upholds rigorous quality standards with meticulous craftsmanship, and continuously deepens its expertise in precision sealing technology. By optimizing its end-to-end quality control systems, the company provides clients across various industries with precision sealing solutions that are stable, reliable, and cost-effective — empowering their long-term growth through superior quality.

To address steadily rising order demand and the increasingly pressing challenge of ensuring stable delivery, Doit Rubber Products Co., Ltd. (international brand: DoitRubber) officially completed a new round of capacity upgrades and facility expansions in the first half of 2026. Grounded in the company’s long-term strategic planning, this expansion aims to achieve a systematic upgrade of production capabilities, thereby guaranteeing more stable and efficient product delivery for global customers.         In recent years, DoitRubber products have gained increasing market recognition, with orders from domestic and international clients continuing to rise. The existing 8,000-square-meter facility has been operating at full capacity for an extended period; workshop space, quality inspection capacity, and warehousing/shipping areas are all nearing saturation, placing significant pressure on delivery lead times. To ensure stable delivery schedules, accommodate large-volume long-term orders, and align with the company’s medium- to long-term revenue growth strategy, the company has launched a project for the systematic expansion of its facilities and the intelligent upgrading of its production lines.       Following this expansion, DoitRubber’s facility area increased from 8,000 m² to 11,000 m² — a net gain of 3,000 m². The additional space is primarily dedicated to enlarging the comprehensive workshop and optimizing the shipping area; this effectively alleviates previous constraints on production space and provides ample room for production line layout and finished product storage.       At the same time, the company has established a new BPA-free workshop compliant with FCM (Food Contact Materials) standards, creating a clean production environment that meets the stringent compliance requirements of high-end clients in sectors such as food and healthcare, thereby expanding its capacity to secure orders in high-end market segments.       The company has simultaneously ramped up investment in automated intelligent equipment, adding five AOI (Automated Optical Inspection) machines and one dual-sided automatic loader. Automated systems now handle repetitive manual tasks across the entire process; front-end automated loading minimizes human error, while back-end visual inspection ensures 100% high-precision product screening. These measures have significantly reduced defect rates and shortened per-unit production times. With concurrent hardware and software upgrades, overall production capacity has increased substantially compared to pre-expansion levels, and delivery times for large-volume orders have been drastically reduced, enabling the flexible, simultaneous scheduling of multiple batches and large orders.       Behind the steady year-over-year revenue growth and capacity upgrades lies Doit Rubber’s consistently strong operational performance. Data shows that the company achieved total sales of RMB 130 million in 2025, driven by stable product quality and comprehensive service. Bolstered by the additional capacity resulting from this expansion, Doit Rubber has set a sales target of RMB 150 million for 2026, steadily advancing toward a larger scale of operations.       Leveraging its exceptional geographical advantages, DoitRubber has established a domestic service network covering the Pearl River Delta, Yangtze River Delta, North China, and Central China, while maintaining a steady supply to global overseas clients. This capacity expansion will further strengthen the company’s ability to handle cross-regional and cross-border orders, supporting simultaneous growth in both domestic and international markets.   Moving forward, DoitRubber remains committed to a customer-centric approach and the continuous improvement of its production processes and management systems. By delivering enhanced production capacity, consistent quality, and efficient delivery, the company will further optimize its operations, deeply explore market demands at home and abroad, and leverage its capabilities in large-scale, intelligent, and standardized manufacturing to establish itself as a benchmark enterprise in the precision manufacturing industry.

As global safety regulations for food-contact materials continue to tighten, “BPA-free” status is evolving from a mere product selling point into a fundamental compliance requirement for an increasing range of food processing equipment, water purification systems, and fluid control products. The European Union is set to implement Regulation (EU) 2024/3190 in January 2025, imposing a comprehensive ban on the use of BPA in food-contact materials, while domestic standards are also progressively lowering permissible limits. For manufacturers, the challenge lies not only in selecting BPA-free materials but also in consistently meeting these rigorous compliance standards over the long term during large-scale production.       A common pattern observed across the implementation of environmental regulations — such as RoHS — is that industries often underestimate the importance of compliance initially, only to face high remediation costs later. A similar trend is emerging in the sector of food-contact materials. As control requirements for specific substances reach the ppm (parts per million) level, even minute variations in raw material management, equipment residues, production environments, and manufacturing processes can impact the consistency of a final product’s compliance. Clients value a supplier’s long-term, stable process control capabilities and mass-production consistency far more than a single passing test result; this is a key reason why an increasing number of international brands prioritize production system management capabilities during supplier audits.   Anticipating regulatory trends regarding food-contact materials, Doit Rubber proactively invested in the development of BPA-free products and the establishment of corresponding production systems. Prior to the launch of its dedicated production workshop, Doit Rubber’s BPA-free sealing products for food-contact applications had already undergone third-party verification by SGS. The test results confirmed compliance with safety standards for food-contact materials, meeting the safety and regulatory requirements for applications such as food processing equipment, water purification systems, and fluid control equipment.     DoitRubber views compliance management for food-contact materials (FCMs) as more than just obtaining a test report; it is a systematic process encompassing the entire lifecycle — from raw materials and production to testing and delivery. Even with a BPA-free formulation, issues such as cross-production, equipment residue, or inadequate environmental controls during manufacturing can compromise product consistency and long-term stability. Consequently, DoitRubber has established a dedicated BPA-free FCM production workshop, implementing independent management for every stage of production — from raw material handling and molding to post-processing.   Regarding cleanliness, the workshop employs an independent access control system featuring a dual-buffer zone. Before entering the production area, all personnel must follow standard protocols — including handwashing, changing shoes, and donning dust-proof caps and suits — to minimize the risk of external contaminants entering the production environment at the source.       Regarding the production environment, the workshop maintains a constant-temperature setting, with the temperature in the production area stably controlled at 23 ± 3°C. Stable environmental conditions help ensure consistency across key processes — such as rubber compounding, molding, and vulcanization — thereby enhancing dimensional accuracy, physical property stability, and batch-to-batch consistency. This guarantees that food-contact products consistently meet relevant standards over the long term.   Currently, the dedicated BPA-free FCM (Food Contact Material) workshop has completed the layout and commissioning of core equipment and has officially entered the mass production phase. The workshop is equipped with four production units, a compounding mill, an automatic cutter, and a post-curing oven. It is capable of independently executing key processes — including milling, cutting, molding, and post-curing of BPA-free food-grade rubber — enabling dedicated production line management for BPA-free products and eliminating potential risks associated with mixed-line production.       For years, DoitRubber has served the sectors of micro-pumps and valves, medical devices, fluid control, and precision sealing, accumulating extensive expertise in dimensional precision, sealing performance stability, and batch-to-batch consistency. The company recognizes that end customers require not merely a batch of products that pass inspection, but a manufacturing capability that consistently meets standards over the long term. The establishment of this dedicated BPA-free workshop for Food Contact Materials (FCM) represents a strategic move by DoitRubber to align with the trend toward enhanced safety in food-contact materials, further strengthening its manufacturing capabilities for food-grade precision seals.   Looking ahead, DoitRubber will continue to advance the automation and intelligent upgrading of its BPA-free workshop. By progressively introducing automated deflashing, AOI (Automated Optical Inspection), and automated packaging equipment, the company aims to build a comprehensive management system covering raw material handling, manufacturing, quality inspection, and clean packaging, thereby achieving independent management of the entire process — from production and inspection to packaging and shipment — for food-contact grade seals.       The official launch of this dedicated BPA-free workshop marks a significant upgrade for DoitRubber in the field of food-contact precision seals, spanning the entire value chain from material R&D and third-party validation to specialized, large-scale production. Moving forward, the company remains committed to providing precision sealing solutions that ensure safety, stability, and long-term regulatory compliance for clients across sectors such as food processing equipment, water purification and fluid handling, medical devices, and high-end pumps and valves.

As global healthcare standards regarding the stability, consistency, and biocompatibility of seals become increasingly stringent, the demand for customized medical seals is surging — driven by diverse application scenarios — and has emerged as a core trend in industry upgrading. Against this backdrop, Doit Rubber Products Co., Ltd. (international brand: DoitRubber) — a specialist in rubber sealing products — has leveraged its technical expertise in medical equipment and consumables to address common industry pain points associated with silicone stoppers for reagent kits. These issues include reagent incompatibility caused by the migration of volatile organic compounds (VOCs) from raw materials, failure to meet cytotoxicity standards, and needle-clogging errors during puncture resulting from the self-healing adhesion of stopper slits. Through targeted improvements in formulations and manufacturing processes, the company has successfully developed mature, localized solutions to resolve these challenges.       Medical silicone seals serve as critical foundational components for medical devices and in vitro diagnostic (IVD) consumables; their quality directly determines the safety of reagent storage and the operational stability of equipment. DoitRubber has designated medical silicone rubber sealing products as one of its core business segments. Its comprehensive product line encompasses a wide array of precision components — including silicone caps for IVD reagent kits, seals for cryovials, specialized silicone sheets for reagents, seals for ventilators, gaskets for nebulizers, and one-way valves for blood pressure monitors — and is widely utilized in key applications such as in vitro testing, respiratory care, and medical consumables.       Regarding quality control, DoitRubber has established a comprehensive compliance system and a Class 100,000 medical-grade clean production workshop, ensuring strict environmental control throughout the entire manufacturing process. Its medical sealing products have obtained multiple authoritative certifications — including ISO 13485 (medical device quality management system) and US FDA approval — and meet biocompatibility testing standards. Leveraging years of practical experience in the mid-to-high-end biomedical market, DoitRubber offers targeted product development based on specific equipment parameters and operating conditions; it flexibly handles OEM and ODM custom orders, precisely meeting the diversified and varied procurement needs of the medical market.       DoitRubber has achieved significant technological breakthroughs regarding silicone caps for IVD (in vitro diagnostic) reagent kits — precision components that undergo frequent piercing and come into direct contact with reagents. The company conducted a systematic, root-cause analysis to address two major challenges prevalent in the industry: first, issues involving the migration of chemical elements from the silicone, material-reagent incompatibility, and failures in cytotoxicity testing; and second, the problem of “self-healing” cuts in silicone products, which obstructs automated assembly probes during piercing and triggers system alarms.   The research revealed that the root causes of these persistent issues lie in several factors: the complex composition and low purity of traditional material formulations; laxity in manufacturing processes and parameter settings; and the incomplete removal of VOC (Volatile Organic Compound) components. Furthermore, the selected silicone materials lacked the inherent capability to prevent cut self-healing; this deficiency, compounded by unscientific manufacturing and storage conditions, accelerated the healing and adhesion of the pierced incisions.       To address this, DoitRubber has opted to utilize high-purity fumed silica or specialized medical-grade silicone — materials proven to pass biocompatibility testing — thereby enhancing material purity at the very source. Concurrently, the company has successfully developed a specialized silicone formulation featuring self-healing capabilities against incisions, while also optimizing conditions for product manufacturing, storage, and transportation to effectively prevent incision adhesion. This series of innovations has successfully resolved persistent issues — such as failures in cytotoxicity testing caused by residual VOCs, and needle-clogging errors during punctures resulting from the adhesion of self-healing silicone septa. Consequently, the safety, stability, and compatibility of DoitRubber’s medical seals have been significantly enhanced, fully meeting the mass production demands associated with the automated assembly of high-end medical equipment.   Currently, China’s domestic medical sealing industry is rapidly transitioning toward greater precision, customization, and regulatory compliance. With material R&D at its core and customized services as its strategic lever, DoitRubber continues to bridge the technological gaps within the domestic sector for precision medical seals. Moving forward, DoitRubber will further intensify its investment in the R&D of novel medical materials and expand its portfolio of medical sealing solutions across diverse application scenarios, thereby contributing to the high-quality development of the entire upstream and downstream supply chain for domestic medical devices.

In the precision rubber industry, equipment can be procured, materials can be substituted, and processes can be replicated; yet, what truly distinguishes one enterprise from another is — above all else — its “people.” In recent years, as competition within the manufacturing sector has shifted from mere scale expansion toward a deeper contest of quality and efficiency, the “human element” has gradually emerged as the central driving force that integrates all other resources — encompassing machinery, materials, methods, and environment. On this competitive track, Doit Rubber Products Co., Ltd. (international brand: DoitRubber) has chosen a path less traveled — yet one with far greater potential for sustained growth: the philosophy that “cultivating talent is more important than simply recruiting it.”       The production of precision rubber products is a competition that tests not only the precision of equipment but, more importantly, the accumulation of experience and the capacity for organizational synergy. From mold development to the molding process, and from defect analysis to batch-to-batch stability, every single stage relies on the judgment, execution, and creativity of both frontline employees and management. DoitRubber deeply recognizes that while machinery serves as the skeleton, and materials and processes constitute the flesh and blood, it is human talent that acts as the heart — infusing the entire manufacturing ecosystem with vitality. The human element permeates the entire production workflow, serving as the critical link connecting intelligent equipment, raw materials, manufacturing processes, and the operational environment; ultimately, the successful implementation of every production stage, the optimization of processes, and the refinement of the overall system are all realized through the expertise of skilled professionals.   Currently, as a wave of intelligent manufacturing transformation sweeps across the entire industrial sector, the precision rubber industry — a core supporting pillar of high-end manufacturing — is witnessing a subtle yet significant shift in the dimensions of industry competition. Compared to mere equipment upgrades or capacity expansion, refined production processes, mature practical experience, and highly efficient internal organizational capabilities have emerged as the core competitive strengths enabling enterprises to vie for market dominance. In response to this evolving industry landscape, DoitRubber has adopted a holistic approach encompassing the “5Ms” of manufacturing — Man, Machine, Material, Method, and Environment. By delving into the fundamental logic underpinning manufacturing development, the company has established a strategic vision centered on “talent as the primary driving force.” Through the construction of a systematic talent development framework, the refinement of diversified incentive mechanisms, the optimization of modern management models, and the deepening of heartfelt employee care initiatives, DoitRubber is comprehensively fortifying the foundations of its corporate growth, thereby forging a path toward high-quality industrial upgrading that is uniquely tailored to the precision rubber sector.       To address critical industry challenges — such as gaps in skilled talent, slow growth among new hires, and the fragmentation of production expertise — DoitRubber has established a standardized, tripartite talent development mechanism. This system integrates mentorship, specialized training, and digital instruction to transform scattered individual practical experiences into standardized, transferable, and replicable organizational capabilities.   Regarding the cultivation of new talent, the company implements a mature “veteran-mentoring-newcomer” model. This initiative focuses specifically on the Tooling and Molding Technology Department, establishing a dedicated apprenticeship program with a structured, tiered growth cycle spanning one to two years. Under the guidance of senior technical veterans providing one-on-one mentorship, new hires undergo a progressive incubation process — ranging from fundamental mold theory and hands-on operations to troubleshooting and process optimization. This approach rapidly bridges practical skill gaps among new employees, thereby building a strategic reserve of technical talent for the company.   In the realm of specialized skills training, the company regularly organizes professional development sessions for its entire workforce, covering all roles across production, quality control, and molding operations. The Quality Control track focuses on defect management, explaining the root causes of various common quality anomalies and demonstrating the practical application of professional analytical tools — such as fishbone diagrams — to empower employees to trace the origins of quality issues and optimize production workflows. The Molding Production track conducts intensive practical workshops covering topics such as the proper use of air guns, standardized machine operation procedures, and the visual identification of defects in finished products; this initiative aims to standardize employee work habits and reduce product scrap rates at the source.       Concurrently, by leveraging digital tools to streamline the training process — specifically for foundational tasks such as ERP system operations and repetitive, standardized procedures — we have produced a library of SOP instructional videos. This allows employees to utilize their spare moments for self-paced learning and repeated review, thereby transcending the constraints of time and space. This approach not only reduces training costs but also enhances overall training efficiency, ultimately facilitating a comprehensive upgrade of the entire workforce’s capabilities.   On the innovation front, we have implemented a company-wide incentive mechanism for improvement proposals. This initiative encourages every employee to draw upon their specific roles to offer optimization suggestions across various domains, including production processes, equipment maintenance, on-site management, and cost control. Once a proposal is adopted and successfully yields tangible results — such as improved quality, reduced costs, or increased efficiency — the proposing employee receives both a corresponding financial reward and public recognition. This strategy serves to guide the entire workforce toward active participation in the company’s refined management practices, harnessing the collective wisdom of all employees to drive corporate advancement.   Beyond the scope of work, DoitRubber places equal emphasis on fostering a sense of “organizational warmth.” Collective activities — ranging from making dumplings during traditional solar terms to enjoying *tangyuan* (sweet rice balls) during the Lantern Festival, or hosting outdoor barbecues — serve as a powerful emotional adhesive among employees. This atmosphere — characterized by “management with rigor, yet care with warmth” — ensures that employees experience both the stimulating pressure of professional growth and the reassuring sense of belonging.       Viewed through the management dimensions of “Man, Machine, Material, Method, and Environment,” equipment can be updated, materials improved, and processes upgraded; yet, it is human talent that serves as the core element — interconnecting all other factors and consolidating the collective force for development. A stable team capability and a mature organizational framework constitute the bedrock upon which an enterprise can achieve steady and sustainable growth. DoitRubber is deeply committed to talent development and organizational optimization, having established an integrated mechanism encompassing talent cultivation, performance evaluation, incentives, and team care to effectively implement lean management practices. By enhancing personnel capabilities and upgrading management systems, the company aligns itself with the evolving demands of process iterations and service enhancements. This approach fosters a virtuous cycle of employee growth, improved management efficiency, and increased customer value — leveraging the meticulous cultivation of talent and organization to safeguard the enterprise’s high-quality, long-term development.

To further enhance its level of production automation, Huizhou Doit Precision Products Co., Ltd. (International Brand: DoitRubber) has recently entered into collaborations with multiple manufacturers of inspection equipment. In recent weeks, several of these partner manufacturers have simultaneously arrived on-site to commence equipment trials and commissioning. The suppliers with whom DoitRubber has recently partnered represent a diverse spectrum of expertise — ranging from technology-driven R&D specialists and providers of mature, mass-production-proven systems to established industry leaders. DoitRubber is employing a rigorous, real-world testing methodology under identical operating conditions to capture comprehensive performance data for each piece of equipment; through comparative analysis, the company will select the most superior suppliers for long-term, in-depth collaboration. This concentrated series of trials and evaluations aims to identify inspection equipment characterized by exceptional compatibility, high operational stability, and advanced intelligence, thereby further refining the company’s intelligent automation framework for quality inspection and solidifying the hardware foundation for the quality control of its rubber sealing products.         In the rubber products industry, traditional manual visual inspection has long been the dominant method; however, its inherent drawbacks are becoming increasingly apparent. Influenced by factors such as visual fatigue, inconsistent subjective standards, and variations in operator experience, manual inspection suffers from a subjective error rate as high as 18%. It demonstrates limited capability in identifying defects — such as microscopic cracks, latent deformations, and minute surface scratches — leading to frequent instances of missed and false detections. Consequently, this method is no longer adequate to meet the high-quality standards required for precision rubber seals. A report published by the China Rubber Industry Association in 2025 revealed that, as of 2024, the overall equipment automation rate within the domestic rubber industry stood at merely 42.7%. This highlights a significant gap in intelligent quality inspection capabilities, making the upgrade to automated and digitized inspection systems an imperative necessity for corporate transformation. Against this backdrop, DoitRubber has taken a pioneering stance, leveraging mature AOI (Automated Optical Inspection) technology to continuously iterate and optimize its intelligent quality inspection solutions.       Leveraging a solid foundation of technical expertise, DoitRubbe specializes in the field of rubber seal inspection. Centered on mature AOI (Automated Optical Inspection) technology, the company continuously refines its intelligent quality inspection solutions. Its proprietary AOI system features a robust hardware configuration — equipped with high-resolution industrial cameras and a multi-angle professional lighting system — and is paired with continuously evolving intelligent image recognition algorithms. This combination enables the precise detection of various surface defects, including burrs, cracks, deformations, and dimensional anomalies. Addressing key industry pain points — specifically the soft texture of rubber seals, their susceptibility to deformation, and the difficulty in identifying latent defects — DoitRubbe has implemented targeted equipment upgrades. These enhancements include the integration of high-definition camera modules, the addition of dynamic compression rollers to simulate real-world operational stress conditions, and the simultaneous updating of its inspection image library. This comprehensive upgrade enables the system to perform dynamic deformation analysis on products, thereby accurately screening for latent defects and meeting the rigorous “zero-defect” procurement standards of high-end clientele.       As a specialized, sophisticated, and innovative “Little Giant” enterprise — as well as a High-Tech Enterprise — dedicated to the R&D and manufacturing of precision rubber products, DoitRubber has long cultivated deep expertise in the field of precision rubber seals.

At Doit Rubber Products Co., Ltd. (International Brand: DoitRubber), the corporate mission is not merely a slogan hanging on a wall, but a warm and ongoing practice. Beginning in March 2025, DoitRubber integrated Kazuo Inamori’s “Amoba Management” philosophy — drawing upon its core tenets of “candid communication and team cohesion” — to put into concrete action the pursuit of “both material and spiritual happiness for all employees.” This initiative gave birth to a unique and distinctive employee program: the “Little Angel Activity.”         The operational mechanism of the “Little Angel” initiative is both simple and deeply thoughtful: organized around “Little Angel” groups, the program revolves around a monthly theme. Each member receives a monthly activity allowance of 50 yuan, with an additional 50 yuan granted to those celebrating a birthday that month. While this stipend may not be substantial in monetary terms, it is imbued with profound emotional value — designated for a wide variety of team activities, ranging from group meals and outdoor excursions to employee care initiatives and social welfare projects.   Each month, the program centers on a distinct theme. From March’s “Innovation and Improvement: It Starts with Me,” to April’s “Grateful for You: Walking Together,” and May’s “The Team’s Most Precious Sparkle — As I See It,” these themes serve as guiding banners. They inspire the team to pursue growth amidst their shared joy, and to truly see and appreciate one another during their times of togetherness.         Led by the Management Department, this initiative empowers each department to independently organize its own activities. Every month, departmental representatives serve as judges to evaluate participating teams; submissions — presented in the form of videos and photos — are assessed based on their entertainment value, thematic relevance, and the department’s “improvement proposals” for that month. Based on these criteria, an “Outstanding Little Angels” team is selected and awarded a bonus of 200 yuan. This mechanism not only sparks creativity but also closely integrates team-building efforts with daily operational improvements, ensuring that “improvement and innovation” is not merely a slogan, but a guiding principle that permeates every aspect of our work.   Among the many activities held, the weekend hiking excursion organized by the “Invincible Battle Team” — a team formed by members of the R&D Department — was particularly moving. As the team hiked together, they noticed a significant problem: litter was strewn carelessly along both sides of the mountain trail. Although no one had assigned this task, and no one was monitoring their performance, the team members spontaneously bent down to help; as they made their way up the mountain, they continuously gathered the discarded bottles, tissues, and packaging wrappers left behind by others.         Upon reaching the summit, everyone gathered beneath the Prayer Tree to offer their blessings, then sat in a circle to enjoy a picnic together. Sunlight bathed every face — sweaty yet beaming with smiles. In that moment, team cohesion ceased to be an abstract concept; instead, it took tangible form in every helping hand extended, every shared bite, and every peal of laughter.   Since the launch of the “Little Angel” initiative, employee relations at DoitRubber have undergone a subtle yet profound transformation. Beyond the workplace, everyone has taken on a new identity — that of a family member with whom one can truly open up. New hires now integrate into the team at a noticeably faster pace; faces that once existed merely across the conference table have become warm, authentic presences — whether on the hiking trail, around the dinner table, or at community service events.   The corporate mission — “to pursue both the material and spiritual well-being of all employees” — has become concrete and palpable through simple acts: a monthly contribution of 50 yuan, a mountain hike, a picnic, or a birthday celebration. It is no longer a grand narrative, but rather a collection of small, everyday moments in which everyone can participate, create, and find fulfillment. When employees begin taking the initiative to plan surprises for one another, when an R&D team spontaneously stops to pick up litter during a hike, or when a newcomer, during an activity, refers to the group as “our team” for the very first time — that is when the vision of “material and spiritual well-being” has quietly taken root. And perhaps, this represents the most unadorned and sincere echo within the corporate world of Kazuo Inamori’s “Konpa” philosophy.

On April 17, 2026, Doit Rubber Products Co., Ltd.,(operating under the international brand “Doit Rubber”) was invited to attend the Supplier Conference hosted by one of its core pump and valve clients. The conference, themed “Navigating Change Together: Stabilizing the Supply Chain and Moving Forward,” focused on supply chain collaboration, technological innovation, and quality enhancement. The event was attended by the client’s Chairman, senior executives, General Managers of various business units, technical specialists, Quality Directors, and SQEs. Representing DoitRubber, our General Manager, Yu Hairong, and Business Representative, Zeng Liyuan, were present to discuss collaborative achievements and explore new pathways for industry development.       This invitation stemmed from our successful efforts to develop rubber products compliant with the new EU regulations regarding the ban on BPA. Following extensive preliminary collaboration and tireless efforts by both parties, the client announced that our products had successfully met the ban’s requirements and passed all necessary testing — an achievement that earned us on-the-spot commendation from the client during the conference. Following the meeting, both parties engaged in in-depth discussions regarding the management and control of mass production details for these products, ensuring comprehensive preparations are in place for the upcoming large-scale manufacturing phase.       During this material development project, DoitRubber effectively addressed technical bottlenecks by proposing and implementing highly efficient solutions. To maximize time savings for both parties, DoitRubber simultaneously developed multiple material samples and submitted them for testing; samples that successfully passed the tests were then selected to create prototypes for the client’s evaluation. This approach significantly reduced the sample confirmation cycle time, thereby creating opportunities for both us and our client to secure orders. Concurrently with the material validation process, DoitRubber renovated and established a dedicated, high-cleanliness workshop to prevent cross-contamination at the source during production, thereby completely eliminating any potential contamination risks.       Leveraging our robust technical capabilities, rapid response times, and consistent quality delivery, DoitRubber has become one of only two suppliers capable of mass-producing seals that meet the client’s BPA testing standards. Currently, the relevant products have entered a small-batch trial production phase and are poised to transition to large-scale supply. During the conference, the client spoke highly of DoitRubber, stating: “Throughout our partnership, DoitRubber has upheld a philosophy of mutual benefit and win-win cooperation. They have demonstrated deep synergy with us in areas such as strategic planning and resource integration, delivering consistent performance and professional service; they are a vital partner in our company’s strategic development.” This recognition serves as both an affirmation of DoitRubber’s capabilities in technological innovation and a testament to the enduring stability of the long-term partnership between our two companies. Currently, as global manufacturing supply chains undergo restructuring, the pump and valve industry finds itself in a critical transitional phase characterized by “enhanced safety, improved environmental standards, and supply chain stabilization.” Moving forward, Doit Rubber will remain steadfast in its development philosophy of “technology as the core, quality as the foundation, and collaborative win-win outcomes.” Leveraging formulation technologies that comply with BPA bans as a strategic fulcrum, we will continue to deepen our expertise in the field of pump and valve seals — constantly iterating our material formulations and production processes while refining our clean manufacturing systems. Simultaneously, we will strengthen strategic collaboration with our core clients to jointly navigate industry shifts. By delivering superior products and more efficient services, we aim to empower our clients to stabilize and fortify their supply chains and expand into high-end markets, thereby collectively driving the pump and valve industry toward high-quality development that is safer, more environmentally friendly, and more efficient.

In active response to our client’s demands for enhanced quality and cost reduction — and with the aim of deepening our strategic partnership — Mr. Yu Hairong, General Manager of Doit Rubber Products Co., Ltd., recently led a delegation — including Sales Representative Ms. Wang Yanyan — on a dedicated on-site visit to our client’s facility. During the visit, the delegation engaged in in-depth discussions and conducted production line surveys with key client stakeholders, including IQC Supervisor Mr. Zou, Quality Manager Mr. Cai, and R&D Manager Mr. Cheng. The discussions focused specifically on core topics such as optimizing the quality of Y-rings and reducing the costs associated with 100% production line inspection, with the shared objective of forging new breakthroughs in our collaborative efforts.         The current market environment is becoming increasingly challenging; while the costs of raw materials — such as plastics and metals — continue to climb, the selling prices of end products face downward pressure, constantly squeezing industry profit margins. Consequently, our client’s production lines are facing an urgent need for comprehensive cost reduction and efficiency improvements.   At the outset of the meeting, the client’s core team candidly articulated their requirements: while the quality stability of the Y-rings supplied by Doit Rubber has improved significantly in recent years — resulting in a substantially higher product pass-through rate and garnering high acclaim — the client’s rigorous “zero-defect” standards necessitate continued investment in their own production line. Specifically, they are required to deploy 3 to 5 dedicated personnel to conduct 100% line-side inspections using microscopes; this results in persistently high labor costs, which have become a major bottleneck in their cost-reduction efforts. The client expressed a desire for Doit Rubber to upgrade its quality control equipment at the source — thereby enabling the efficient interception of defective products — to completely eliminate the need for manual 100% inspection on their production lines and achieve tangible reductions in operational costs.       Directly addressing these client pain points, General Manager Yu Hairong and his team immediately proceeded to the production front lines to observe the client’s entire Y-ring inspection process firsthand. On-site observations confirmed that the client employs an inspection methodology involving “dynamic flattening” and multi-angle defect identification. This approach is significantly more rigorous than Doit Rubber’s current static AOI (Automated Optical Inspection) standards, which explains the discrepancy between the two parties’ inspection criteria and constitutes the core reason why the client has been compelled to conduct additional 100% inspections.       In response to this critical issue, Doit Rubber’s team conducted a rapid on-site assessment and formulated a precise, systematic solution: upgrade the existing AOI inspection equipment by installing high-definition cameras and integrating a “dynamic compression wheel” mechanism to simulate real-world product deformation. Concurrently, the AOI inspection image library will be updated to fully align with the client’s dynamic inspection standards, thereby enabling the precise and efficient interception of all defective products. This comprehensive solution not only ensures that Doit Rubber meets the client’s “zero-defect” requirements at the source but also completely eliminates the need for manual 100% inspection on the client’s production lines, thereby empowering the client to achieve substantial cost savings. Both parties agreed that the implementation of this solution would result in a win-win outcome: for the client, it would significantly optimize the cost structure of their production lines; for Duyite, it would drive product quality to new heights, further solidify deep client trust through robust technology and service capabilities, and cement the foundation for a long-term strategic partnership.       Following the thematic discussion, and at the introduction of Supervisor Zou, General Manager Yu Hairong and his delegation paid a special visit to Manager Liu of the client’s R&D Department II. They engaged in in-depth discussions regarding technical and cost-related issues for a new pre-development project — specifically focusing on O-ring tolerance control and the optimization of self-lubricating O-rings. The two sides engaged in a comprehensive exchange of ideas concerning new material applications, process optimization, and precise tolerance management, thereby clarifying the collaborative roadmap for future progress and laying a solid foundation for the successful launch of the new project and effective cost management.       This visit serves as a vivid demonstration of Duyite’s commitment to its “customer-centric” philosophy, as well as a pragmatic initiative focused on addressing key client pain points and working together to overcome challenges. Moving forward, Duyite will remain guided by customer needs, accelerating the implementation of the equipment upgrades and technical optimizations identified during this visit to ensure they yield tangible results. By continuously strengthening quality control and innovating its service models, Duyite aims to join hands with its clients to navigate market challenges and embark together on a path of high-quality development characterized by cost reduction, efficiency gains, and mutual benefit.

In recent years, the global trend of restricting PFAS (per- and polyfluoroalkyl substances) has become increasingly clear. Meanwhile, end consumers are paying growing attention to drinking water safety and environmental standards, driving continuous upgrades in material selection for related products. Against this backdrop, European and American pump and valve customers have put forward higher requirements for precision rubber seals used in key sealing positions. On the basis of ensuring stable sealing performance, the seals must be BPA-free, comply with the LFGB food contact standard, and adopt a fluorine-free material formulation. This shift indicates that the material selection logic for seals is gradually changing from the traditional "performance first" to "equal emphasis on performance, safety and environmental protection".       To meet these new requirements, Doit Rubber Products Co., Ltd. (hereinafter referred to as "DOIT") has carried out collaborative development with material suppliers and leading customers in the pump and valve industry. In the project, material suppliers are responsible for providing fluorine-free modified formulation solutions; DOIT conducts formula adjustment, material mixing and process control based on the formulation, and completes seal molding; customers then carry out complete machine assembly and application testing and verification. After 12 months of collaborative promotion in material development, process adaptation and terminal testing, the relevant solutions have been gradually implemented.   The seals developed with this formulation are mainly used in key sealing nodes of the internal waterway systems of water dispensers and coffee machines, and are widely applied to dynamic and static sealing parts of pump and valve components. They are key components in direct long-term contact with drinking water. In such application scenarios, seals not only need to have basic sealing performance, but also meet stricter usage requirements, including stability during long-term contact with drinking water, structural reliability under thermal cycling conditions, and continuous resilience performance in high-temperature environments.       Achieving stable and reliable performance under a fluorine-free material system is the core technical difficulty of this development. In the scenario of pump and valve dynamic sealing applications, the resilience stability and sealing reliability of materials under repeated start-stop and pressure fluctuations are particularly critical. Compared with traditional fluorine-containing materials, fluorine-free materials need optimized compensation through formulation and process in terms of temperature resistance, chemical stability and compression set control. Meanwhile, the strict restrictions of the LFGB standard on material components and migrants have imposed higher compliance requirements on the entire production process. The large-scale application of fluorine-free materials is essentially a systematic verification and breakthrough in material system, mixing process and molding stability.   After one year of repeated production and testing, this food-grade sealing solution has passed customer application verification and meets the established usage requirements and relevant standards. This proves that seals meeting BPA-free and food contact standards can also achieve stable and reliable application performance under strict performance and regulatory constraints.       From the perspective of industry development, DOIT's practice has further verified the application feasibility of food contact standard-compliant sealing solutions in the high-end water equipment field. With the continuous tightening of environmental regulations and the increasing market attention to healthy and sustainable materials, the development direction of seal materials is accelerating the transformation to safety and environmental protection.   In this process, DOIT has completed the verification from material adaptation to mass production feasibility, further enhanced its customized sealing solution capability in the high-standard food contact application field, and also provided a reference path for material selection and application of food contact seals in pump, valve and fluid control equipment.

As manufacturing competition shifts from production scale to technological density, innovation capability is evolving from a “value-add” into a prerequisite for survival. For precision manufacturing enterprises, the continued expansion of downstream markets — driven by the surge in the new energy vehicle industry, advancements in medical device technology, and the rapid iteration of smart electronics — imposes rigorous demands on the supply chain. It requires not only zero-defect delivery but also a comprehensive test of R&D responsiveness, quality traceability, and the potential for continuous iteration. Against this backdrop, R&D capability is no longer merely the function of a single department; it has become a strategic pivot point through which an enterprise defines its own value.         The practices of Doit Rubber Products Co., Ltd. (international brand: DoitRubber) offer a micro-level perspective on this trend. Its R&D capability building is not merely a matter of isolated laboratory investment but a structured, multi-tiered system for tackling technical challenges: a core R&D team of 15 serves as the hub, three specialized R&D groups act as the vanguard for key breakthroughs, and a technical engineering team of over 30 handles the translation of results into practice. This architecture ensures a seamless transition from fundamental material research to the implementation of mass-production processes. The company has amassed over 30 patents covering structural design, process optimization, and sealing solutions — achievements that represent not only tangible technical barriers but also a repository of knowledge reflecting the company’s understanding of customer pain points and its ability to anticipate industry trends.         The true value of R&D lies in translating innovative capabilities into tangible manufacturing realities. In product development, DoitRubber demonstrates more than just mold design expertise; it engages deeply from the very source — material application and selection. Its ability to optimize sealing solutions and offer flexible, customized development signifies a capacity for collaborative R&D with clients, moving beyond the role of a passive manufacturer working from blueprints. This evolution from mere “manufacturing execution” to “collaborative R&D” marks a pivotal step for a precision manufacturing enterprise seeking a higher position within the value chain.   A robust quality assurance system serves as the vertical extension and closed-loop support for these R&D capabilities. By implementing a quality management model that spans the entire lifecycle — from R&D and production to inspection — and by adopting advanced technologies like Automated Optical Inspection (AOI), the company demonstrates a quality philosophy that transcends simple final inspections; instead, it prioritizes quality achieved through upfront design and comprehensive process control. Obtaining certifications such as ISO9001, IATF16949, and ISO13485 not only grants market access but also establishes a standardized framework for effective communication with global clients. Building on years of deep technical expertise, the company has been recognized as a “National High-Tech Enterprise” and a “Specialized, Refined, Distinctive, and Innovative” (SRDI) SME. Leveraging this solid foundation, DoitRubber is now actively pursuing designation as a national-level SRDI “Little Giant” enterprise.         The reason R&D innovation serves as a source of long-term competitiveness for precision seal manufacturers lies in its ability to foster an “antifragile” development structure. In an era of rapid technological iteration and volatile demand, only enterprises capable of continuous learning and evolution can transform uncertainty into opportunity; the drive to achieve the status of a national-level “Little Giant” (specialized, refined, distinctive, and innovative enterprise) powerfully validates this logic — it represents not merely a static review of past achievements, but a dynamic recalibration for the competitive landscape of the future.   Ultimately, competition in precision manufacturing is a contest defined by both the depth of R&D capabilities and systemic efficiency. As more enterprises come to realize that the number of patents does not equate to true innovation capacity — and that system certifications do not guarantee quality — the decisive factor separating the leaders from the rest will be organizational capability: the ability to weave R&D, engineering, quality control, and production into a cohesive, organic network. DoitRubber’s experience demonstrates that excelling in the niche sector of precision rubber and silicone seals requires more than just advancements in materials science and manufacturing processes; it demands a corporate mechanism capable of continuously generating, validating, and translating innovative outcomes. This mechanism may well be the most reliable source of certainty for precision manufacturing enterprises navigating an uncertain era.

On November 6, 2025, at the 8th China International Import Expo, YHLO, a leading domestic in vitro diagnostic (IVD) enterprise, and Sanofi, a global healthcare giant, jointly launched the "China Type 1 Diabetes Ecosystem Co-construction Cooperation Alliance".

For example: adding talcum powder, spraying Teflon or parylene on the surface.This offers a number ofbenefts during installation by -Reducing the installation forces -Non-stick effects, easy removal The handling and installation of dimensionally unstablecomponents requires a great deal of experience.   Reliableautomated installation thus demands special handling and packingofthe O-Rings.   Please ask our specialists for further details. Installation that requires crossing threads and splines:Installation Over Threads, Spines, Etc. Should the O-Ring have to be stretched over threads, splines,keyways etc., then an assembly mandrel is essential.   This mandrelcan either be manufactured in a soft metal or a plastic materialobviously without burrs or sharp edges. Installation suggestions:Before starting installation, check the following points. Lead-in chamfers made according to drawing? Bores deburred and edges rounded? Machining residues, e.g. chips, dirt and foreign particles, removed? Screw thread tips covered? Seals and components greased or oiled? Ensure media compatibility withthe elastomer material. Do not use lubricants with solid additives, e.g. molybdenum disulphide or zinc sulphide. Solution 1、Cleanliness Foreign particles such as dust, dirt, metal chips, grit in the groovemay cause leakage and can damage the O-ring. Cleaning materialmust also be a medium which is compatible with the elastomer 2、Stretch The inside diameter expansion to reach the groove duringassembly should not exceed 50%, For very small diameters, it isnecessary to cxcced this limit, If so, suficient time should beallowed for the O-ing to return to its normal diameter beforeclosing the groove assembly. 3、Lubrication For static and dynamic applications lubrication is important forease of assembly, The greatest beneft in using a lubricant isobtained during the initial installation of the O-ring.   Grease usedto ease assembly must be compatible. Do not use a lubricantcomposed of the same material as the O-ring. For example,silicone grease can be effectively used on EPDM seals, but notrecommended for VMQ seals. Common lubricants for O-rings are: 1)Hydrocarbon-based materials: Such as petrolatum, betterknown as petroleum jelly-Vaseline®, But it is also availablein liguid form. 2)Silicone-based greases: Such as Dow Coming DC-55, ageneral-purpose grease.   Silicone-based greases have a wideworking temperature range and are compatible with severalkinds of rubber materials. 3)Barium-based greases: For high temperature applications andapplications requiring chemical compatibility. 4)Other formulations: Such as Celvacene®, Celvacene containsno silicone and is specifically engineered for use in highvacuum pump applications.   As a professional design and manufacturing company specializing in precision rubber products with 15 years of industry experience, DOIT has established a benchmark in niche segments by leveraging its outstanding technical capabilities: The global market share of its automotive O-ring seals reaches 40%, while its Micro Pump Seal (a core component for micro-pump-valve systems) leads the industry in both dimensional precision and service life - outperforming competitors in ensuring leak-free performance for miniature fluid control devices.
