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 are the installation advantages of split PTFE piston rings and guide rings in air compressors?
A:
The split structure allows radial installation into the piston groove without removing the crankshaft, connecting rod, or the entire piston rod, making on-site maintenance and quick replacement much easier. The matched joint gap maintains a continuous, stable sealing face after installation and reduces downtime.
Q:What functions do the piston ring and guide ring serve respectively? Why use them together?
A:
The piston ring mainly maintains the pressure boundary of the compression chamber and reduces gas leakage. The guide ring carries the piston's side load, isolates metal-to-metal contact between piston and cylinder wall, and reduces off-center wear. Used together, they improve both sealing performance and running smoothness, extending cylinder and ring life.
Q:Are the piston ring and guide ring made of pure PTFE or modified PTFE? How do I choose?
A:
Selection depends on service conditions. Pure PTFE offers good chemical inertness and low friction; modified PTFE (filled with carbon fiber, glass fiber, graphite, etc.) improves creep resistance, wear resistance, and dimensional stability. For air compressors with higher side loads, temperature fluctuations, or insufficient lubrication, modified formulations are recommended for both guide and piston rings. We can help recommend.
Q:Can dimensions be customized? Can you machine non-standard rings per drawings?
A:
Yes. Inner diameter, outer diameter, thickness, joint type, and angle can all be customized to your drawings. We accept PDF/CAD 2D drawings and IGES/STEP 3D models, machining round, stepped, and special cross-section rings to match different compressor groove designs.
Q:How is the split ring joint gap controlled? Will it leak or stick-slip after installation?
A:
The joint gap is designed based on cylinder bore, operating temperature, and material thermal expansion coefficient, ensuring the gap closes at operating temperature without excessive interference. Install with the recommended clearance, and piston ring preload maintains sealing. For large pressure fluctuations, joint angle adjustment or backup rings can be used; we can provide installation recommendations.
