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:Why is molded tube recommended over extruded tube for sliding bearings and guide rings?
A:
The molding process allows higher carbon graphite loading with more uniform distribution, yielding higher density and extremely low porosity. Molded tubes therefore offer greater compressive strength, rigidity, and dimensional stability, making them better suited for bearings and guide rings under continuous load and sliding friction.
Q:What specific performance improvements does carbon graphite filling bring to PTFE tubes in sliding bearings?
A:
Carbon graphite significantly improves wear resistance and creep resistance, lowers friction coefficient, enhances self-lubrication, and improves thermal conductivity, helping dissipate friction heat, reduce thermal deformation, and extend bearing and guide ring service life.
Q:Is it suitable for oil-free lubrication? Can it be used underwater or in wet environments?
A:
It is ideal for oil-free lubrication. The carbon graphite filling provides excellent self-lubrication without additional grease. PTFE itself does not absorb water, so it is also suitable for underwater or wet environments without swelling or hydrolysis.
Q:What is the size range of molded tubes? Can they be customized per drawings?
A:
Molded tubes: OD 30-1323 mm, ID 10-1217 mm, length 100-300 mm, all customizable. We accept 2D (PDF/CAD) and 3D (IGES/STEP) drawings and can perform secondary machining such as turning, slotting, and drilling.
Q:How should the fit clearance with a metal shaft be determined during installation?
A:
We recommend allowing proper thermal expansion clearance based on operating temperature and shaft material. A light press fit or clearance fit is usually preferred to avoid deformation from interference. We can provide fit recommendations for your specific conditions.
