Conclusion

How to find a precision stamping parts supplier? In short: First-hand and certification (To identify a first-hand manufacturer, pay attention to whether they have an independent mold processing workshop and stamping production line, and ask to see their business license and business scope including production projects. Directly communicate with the manufacturer’s technical personnel to assess their familiarity with process parameters, effectively eliminating pure trading companies. Have physical production facilities and actively invite customers to visit the factory to show actual production equipment. Jingdezhen News Network; For automotive or similar parts, confirm RoHS, IATF16949 and other system certifications, assess sampling speed and cooperation, prioritize those that provide DFM support, drawing review meetings, and clearly agree on sample delivery nodes. Observe the service attitude for small batch orders.
