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:What is a non-standard over-size sintered PTFE thick slab?
A:
Regular molded PTFE sheet is limited by mold dimensions, while this product is designed for sizes or thicknesses beyond standard ranges. Using custom molds and sintering, we produce one-piece slabs with extra-large diameter, length, or thickness, reducing joints and improving structural integrity and sealing reliability.
Q:What is the maximum thickness and size? Can you customize beyond the specification table?
A:
Standard molded sheet: thickness 3-100 mm, width 150-2000 mm, length up to 2000 mm. For non-standard over-size requirements, we can discuss larger dimensions such as extra width, length, or thicker billets. Please provide your specific sizes for mold and sintering feasibility evaluation.
Q:How does the sintering process affect thick slab performance?
A:
Sintering fuses PTFE powder particles into a dense three-dimensional network, significantly improving density, compressive strength, and creep resistance. For thick slabs, uniform sintering avoids internal porosity and delamination, ensuring dimensional stability and sealing performance after CNC machining.
Q:Is this white PTFE molded sheet suitable for CNC machining?
A:
Yes, it is highly suitable. The sintered molded slab offers excellent machinability for turning, milling, drilling, tapping, slotting, and engraving. We can machine it into seal rings, valve seats, insulators, liners, guide components, and other precision parts per your 2D/3D drawings.
Q:Is the white PTFE sheet FDA-compliant for food contact?
A:
Pure white PTFE molded sheet meets FDA 21 CFR 177.1550 for food contact, along with ROHS and REACH regulations, and MSDS is available. It can be used in food processing equipment, pharmaceuticals, and medical devices. If fillers (e.g., glass fiber, carbon) are added, it is no longer FDA-compliant.
