What is the lead time for delivery?

Standard products typically take 7-15 days, while custom parts require 2-4 weeks depending on complexity (subject to confirmation after order placement).

How do you ensure the pressure and temperature resistance of seals?

We optimize material selection, conduct simulation tests, and implement strict production process controls (e.g., sintering, machining) to ensure performance compliance.

Do you offer technical support and samples?

Yes, we provide free technical consultation and can send samples based on project needs (some samples may incur a nominal cost fee).

How are products packaged and shipped?

We use dust-proof and moisture-proof packaging, with options for vacuum bags or wooden cases. Global logistics (air/sea/express) are supported.

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.
