AI-Powered supplier vetting
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:How are the 'self-lubricating' and 'wear-resistant' properties achieved, and what fillers are used?
A:
By adding solid lubricants (e.g., graphite, MoS2) and wear-reinforcing materials (e.g., carbon fiber, glass fiber, bronze powder) into the PTFE matrix, we significantly reduce friction coefficient and improve abrasion resistance. We recommend the optimal filler combination based on your sealing duty - reciprocating, rotary, or high-pressure.
Q:What sealing assemblies is this tube primarily used for, and what advantages does it offer over rubber or pure PTFE seals?
A:
It is ideal for piston seals, guide rings, shaft sealing bushings, and valve stem seals. Compared to rubber, it withstands higher temperatures and nearly all chemicals; compared to pure PTFE, it offers higher compressive strength, creep resistance, and wear resistance, maintaining a stable sealing gap with lower leakage risk.
Q:Which chemicals can it resist? Is it suitable for strong acids, strong alkalis, or solvents?
A:
The PTFE matrix resists almost all strong acids, strong alkalis, and organic solvents. Fillers (carbon fiber, graphite, MoS2, etc.) are chemically inert and do not compromise corrosion resistance. Only bronze may be affected by strong oxidizing acids - we can offer metal-free formulations for such media.
Q:What dimensions and shapes can be customized? Can you machine it into sealing rings or grooved bushings?
A:
ID, OD, wall thickness, and length are fully customizable. We can also machine complex cross-sections such as sealing rings, guide strips, lubrication grooves, or seal grooves per your drawings. We accept 2D (PDF/CAD) and 3D (IGES/STEP) files.
Q:Should I use interference fit or clearance fit during installation? Do I need additional lubricant?
A:
We generally recommend a light interference press-fit (interference about 0.1-0.2% of shaft diameter) or clearance fit, depending on the seal design. Due to the self-lubricating nature, no extra lubricant is required for installation; however, if press-fit force is high, a small amount of silicone oil or sealing grease may be applied.
