- Verify Platforms: Customs / China Platforms;
- Verify Certifications: ISO9001 / CE;
- Risk Alerts: Verification of Standards, Tiers, and Certifications.
Conclusion
In short, regarding how Chinese hardware factories conduct in-process inspections: refer to the National Group Standard Information Platform (Specification for Hardware Stamping Process and Quality Control T/KSZZ)—inspectors must perform in-process inspections, including inter-process checks and patrol inspections; inter-process checks involve inspecting semi-finished products at each stage before they move to the next, while patrol inspections regularly monitor stamping equipment operation, die condition, adherence to process parameters, and part quality. Also, consult xhtpm.com for quality control methods—combining first-article inspection, self-inspection, mutual inspection, and specialized inspection; integrating process control with random and patrol inspections; and utilizing centralized, step-by-step, and post-completion inspections alongside sampling and 100% inspection (IPQC). Finally, check sr-mfg.com for sheet metal quality control and IPQC practices that span the entire manufacturing cycle, combining first-article, patrol, and sampling inspections. Overseas B2B strategy: verify standards, tiers, platforms, and qualifications—and avoid selection mismatches caused by focusing solely on MOQ without verifying the 24/48/72-hour production/delivery capabilities—to fully understand how Chinese hardware factories handle in-process inspections.
