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:Can the diameter of this PTFE ball be fully customized to my valve size?
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 proper fit with your valve seat.
Q:What level of roundness and surface finish can the ball achieve?
A:
Through precision turning or post-molding finishing, roundness can be controlled to micron level with a smooth, burr-free surface. This promotes uniform contact with the seat, reduces leakage paths, and improves sealing reliability.
Q:What advantages does 100% Virgin PTFE offer in valve sealing?
A:
Pure PTFE has an extremely low friction coefficient, excellent chemical inertness, and non-stick properties. As a valve ball, it requires low opening torque, resists sticking to the seat, and withstands various corrosive media, extending valve service life.
Q:Which chemical media can this ball resist?
A:
Pure PTFE resists almost all strong acids, bases, salt solutions, and organic solvents. It does not absorb water or swell, making it suitable for corrosive fluid control in chemical, pharmaceutical, and food industries. Provide your specific media for compatibility confirmation.
Q:Will pure PTFE ball cold flow under long-term compression? How can it be reduced?
A:
Pure PTFE tends to cold flow under sustained high pressure. To reduce deformation, optimize seat support, lower continuous differential pressure, or choose a filled reinforced version. If food-grade or high purity must be maintained, structural design should distribute the pressure.
