SummaryZhenjiang Chunhuan Sealing Materials Co., Ltd. (Group) is identified as a manufacturer and trading company with its own export license, 186 employees, and more than 30 years of operating history. It produces PTFE sheets, rods, gaskets, and related plastic products, and reports ISO9001, MSDS, RoHS, REACH, and ASTM 3308 credentials. The supplier supports extensive customization and has documented inspection, corrective-action, complaint-handling, and traceability procedures. It reports inventory capability, one-month average lead times in both peak and off-season, and 20 years of export experience. However, it does not provide 3D software design services, has no available SDK, overseas warehouse, overseas showroom, overseas agent or branch, and has not participated in offline trade shows. No valid manufacturing-capacity contract with related subcontractors is reported. Financial information is referenced for 2020–2022, but the provided slices do not disclose sufficient financial results to assess...
Supplier typeThe supplier is explicitly described as both a manufacturer and trading company with its own export license. Its stated activities include manufacturing plastic products and processing machine elements and spare parts, supporting classification as a manufacturing-oriented supplier.
CertificationsThe supplier reports ISO9001, MSDS, RoHS, REACH, and ASTM 3308 credentials, while the sustainability-related certification is specified as ISO9001:2015. These stated certifications provide explicit evidence of certification holdings, although the slices do not verify their scope or current validity dates.
After-Sales capabilityThe supplier has clear procedures and followed records for handling customer complaints, as well as corrective and preventive actions. This directly supports an established after-sales issue-management process.
Production capacityThe supplier identifies itself as a manufacturer with 186 employees and established plastic-product production, reports in-stock capability, and states one-month average lead times in both peak and off-season. However, it also reports no valid manufacturing-capacity contract with related subcontractors, so the evidence demonstrates internal production capability but leaves outsourced-capacity controls as a limitation.
Customization capabilityThe supplier explicitly offers customization from samples, full customization, customization from designs, minor customization, and flexible customization. This is direct evidence of a broad customization service range.
Product Q&A
Q:In a check valve, how does the ball ensure reliable sealing? What about roundness and surface finish?
A:
The ball is precision turned or post-molded and finished, with roundness controlled to micron level and a smooth, burr-free surface. This ensures uniform contact with the seat, reduces leakage paths, and maintains tight sealing even at high temperatures for reliable one-way sealing.
Q:Can you customize the ball diameter and tolerance to my check valve dimensions?
A:
Yes. We support non-standard diameter customization, from small sizes to larger specifications. Just provide the target diameter, tolerance, and quantity. We machine per drawing or sample to ensure a precise fit with your seat.
Q:Which chemical media can this ball resist? Does it remain corrosion-resistant at high temperatures?
A:
Pure PTFE resists almost all strong acids, bases, salt solutions, and organic solvents. Its chemical inertness remains essentially unchanged at high temperatures, making it suitable for corrosive high-temperature fluids in chemical, pharmaceutical, and food industries. Provide your specific media and temperature for compatibility confirmation.
Q:Under prolonged high-temperature compression, will a pure PTFE ball cold flow? How can it be reduced?
A:
Pure PTFE tends to cold flow under sustained high pressure and temperature. To reduce deformation, optimize seat support, lower continuous differential pressure, or choose a filled reinforced version (not suitable for FDA or high-purity applications). If pure PTFE must be maintained, structural design should distribute the pressure.
Q:Is this ball FDA-compliant or food-grade?
A:
Pure PTFE grades typically meet FDA 21 CFR 177.1550 for food contact and can be used in food, pharmaceutical, and potable water systems. Batch-specific compliance statements are available; please specify food-grade requirements when ordering.
