A Absolutely. We implement a comprehensive heat traceability management system; every delivered batch is accompanied by a material certificate and a mechanical properties report, fully meeting the rigorous information requirements of the automotive supply chain as stipulated by IATF 16949.

A Certainly. We operate six forging production lines and maintain a fully equipped in-house CNC machining workshop. Based on your technical drawings or physical samples, we can rapidly develop the necessary molds and manufacturing processes, offering a one-stop customized service ranging from collaborative design to rapid mass production.

A Through a combination of precision turning and multi-axis machining center operations, the surface roughness of our sealing surfaces consistently reaches Ra 0.4–0.8 μm. Critical mating dimensions are controlled within IT6–IT7 tolerance grades, thereby fully guaranteeing reliable high-pressure sealing performance.

A We are committed to a "zero-defect" objective. Should any quality discrepancy be confirmed as our responsibility, we immediately initiate an emergency response process for product replacement or rework. Concurrently, we conduct a root cause analysis and implement preventive measures to ensure the issue does not recur—a process executed with complete transparency and efficiency.

A The lead time for regular, stable orders typically ranges from 20 to 35 days, depending on the complexity of the manufacturing process. We have established a flexible capacity mechanism and an expedited production channel; upon coordination, we can prioritize scheduling for your urgent assembly requirements, providing special handling for critical situations.
