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:Diameters from 5 to 350 mm and custom lengths are offered. Can you provide non-standard sizes?
A:
Yes. We support standard and non-standard diameters, with lengths cut to order. Just provide specific dimensions, tolerances, and quantity. We can also machine per 2D/3D drawings.
Q:Is pure PTFE rod sufficient for guide rings? When do I need filled reinforcement?
A:
Pure PTFE offers chemical resistance and low friction, suitable for light loads, corrosive environments, and food/pharmaceutical contact. However, its load capacity and creep resistance are limited. For guide rings under high pressure, high frequency, high temperature, or heavy loads, choose carbon fiber, glass fiber, or bronze filled grades to improve wear resistance and dimensional stability.
Q:What fillers are commonly used, and how do they help guide ring performance?
A:
Carbon fiber improves creep resistance, rigidity, and wear resistance. Glass fiber boosts strength and optimizes cost. Bronze enhances thermal conductivity and load capacity. Graphite and molybdenum disulfide reduce friction and enhance self-lubrication. Choose the formulation based on pressure, speed, temperature, and media.
Q:Is this rod easy to machine into guide rings? Can you machine per drawings?
A:
Very easy. PTFE rod offers excellent machinability for turning, milling, drilling, slotting, and cutting, with dimensional stability and minimal deformation. We accept PDF/CAD 2D drawings and IGES/STEP 3D models, delivering finished guide rings and other components directly.
Q:Guide rings are under long-term pressure. Will pure PTFE cold flow? How much do fillers improve it?
A:
Pure PTFE tends to cold flow under sustained pressure. Carbon fiber or glass fiber filling significantly reduces compression set, maintaining guide ring dimensions and sealing force - better suited for hydraulic cylinders, pneumatic cylinders, and other continuously loaded applications.
