Kunshan Xinzhenpin — Purity in Every Pore
Kunshan Xinzhenpin New Thin Film Material Technology Co., Ltd.
Established in 2018, Kunshan Xinzhenpin is a specialized manufacturer dedicated to ePTFE waterproof and breathable membrane solutions. We operate a fully integrated production chain covering ePTFE raw membrane manufacturing, composite and post-treatment processing, precision converting, and fully automated assembly of finished venting products. Our manufacturing floor is equipped with advanced equipment including precision rotary die-cutting machines, slitting machines, 2D optical measurement systems, and ultrasonic welding machines, complemented by in-house testing facilities such as air permeability testers and hydrostatic pressure testers. With a current production capacity utilization below 60%, we maintain ample headroom for rapid order fulfillment — our membrane line delivers 3 meters per minute, and vent plug assembly reaches 20,000 units per 8-hour shift per line.
Quality is engineered into every step. All processes are governed by autonomous automated control, and we conduct 100% air permeability testing on finished products to guarantee consistent field performance. Core ePTFE raw materials are imported to secure stable premium quality, while we also offer domestically produced process-grade membranes that deliver reliable performance with superior cost advantages and greater supply flexibility. Our team of 30 includes 6 management professionals and 6 dedicated technical specialists, whose deep expertise is reinforced by a rich portfolio of customized solutions for unique customer applications. This, combined with industry-leading technical reserves, in-house mastery of core treatment technologies, and high levels of production automation, forms the foundation of our distinct cost efficiency.
We hold internationally recognized certifications including IATF 16949, ISO 14001, and GB/T 24001, underscoring our commitment to automotive-grade quality management and environmental responsibility. Our comprehensive product portfolio encompasses vent membranes, vent plugs, vent valves, vent caps, vent gaskets, acoustically transparent membranes, and desiccant components, serving demanding markets such as automotive, new energy, outdoor electronics, and medical devices. At Kunshan Xinzhenpin, we deliver certified excellence through precision manufacturing, rapid responsiveness, and a genuine partnership approach.
We deliver end-to-end ePTFE venting solutions that span from material science to precision manufacturing. Our comprehensive portfolio includes waterproof breathable membranes, vent plugs, valves, caps, gaskets, acoustically transparent membranes, and desiccant components — each engineered to meet the most demanding protection and pressure equalization requirements. Leveraging a vertically integrated production chain, we offer full customization in pore size, thickness, airflow, and water entry pressure, paired with both imported premium ePTFE and high-performance domestic alternatives for optimal cost flexibility. Every product undergoes 100% automated air permeability testing and rigorous in-house validation to ensure consistent field performance. Serving automotive, new energy, outdoor electronics, and medical device sectors under IATF 16949 and ISO 14001 certified systems, we translate complex performance requirements into reliable, ready-to-deploy venting solutions with responsive engineering support and fast sample turnaround.
Founded in 2018, Kunshan Xinzhenpin began with a singular focus: advancing ePTFE venting technology through precision engineering and quality discipline. From our earliest operations, we invested in building a fully integrated manufacturing platform — establishing in-house lines for ePTFE raw membrane production, composite and post-treatment processing, precision converting, and fully automated product assembly. This foundation enabled us to rapidly achieve automotive-grade quality standards, earning IATF 16949, ISO 14001, and GB/T 24001 certifications that underscore our commitment to excellence and environmental stewardship. With an annual sales trajectory reaching USD 1,000,000–2,000,000 and sustained growth, we have evolved into a trusted partner for global brands, all while maintaining ample production capacity to respond with speed and scale. Every step of our journey reflects a deliberate balance between technical depth, operational efficiency, and customer-centric innovation.
Behind our manufacturing precision stands a team of 30 professionals where technical mastery meets operational discipline. With 6 management experts and 6 dedicated R&D and process engineers, we maintain in-house ownership of all core treatment technologies — from membrane microstructure design to automated production control. Our technical specialists bring an extensive library of practical case studies, having solved unique waterproofing and venting challenges across diverse customer applications. This concentrated expertise, supported by advanced automation and autonomous process control, drives not only uncompromising quality but also the cost efficiencies that define our market edge. Led by Founder & General Manager Li Ting, the team operates as a cohesive unit committed to one principle: transforming material science into measurable customer value, project by project.
