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:Is the external thread on this flange plate standard or customizable?
A:
The thread can be fully customized to your requirements - we support metric (M), inch (UNC/UNF), pipe threads (NPT/BSPT), as well as non-standard profiles or special pitches upon request.
Q:What thread tolerance grade can your CNC machining achieve?
A:
We typically control the pitch diameter and flank form to ISO 6H or tighter, using three-wire measurement and thread gauges for verification, ensuring leak-free mating with the internal thread.
Q:Can the flange dimensions (OD, ID, thickness, thread length) be fully customized from my drawing?
A:
Yes. We accept PDF, CAD (2D), and IGES/STEP (3D) files to produce any custom dimensions - including flange outer diameter, bolt hole pattern, sealing boss height, and more.
Q:Is this flange plate made of virgin PTFE or filled PTFE? How does that affect thread machining?
A:
The default is virgin PTFE for maximum chemical purity and non-stick properties. For higher mechanical strength or creep resistance, we can use glass or carbon filled grades, but fillers may reduce surface finish - we compensate with adjusted tooling parameters.
Q:Will high temperature or chemical exposure affect the thread fit?
A:
PTFE has a higher thermal expansion coefficient; we compensate by adjusting thread dimensions based on the difference between ambient and operating temperatures. Also, pure PTFE resists almost all media, so the thread will not corrode or change shape.
