What is the quality control process? How to ensure consistent quality of bulk products?

Adopt a full-link quality control process: Incoming Material Inspection → In-Process Inspection (laser cutting precision/bending angle) → Semi-Finished Product Testing (load-bearing/protection level) → Finished Product Full Inspection (dimensions/surface treatment/accessory assembly) → Pre-Delivery Sampling (simulated ocean shipping vibration test). Each product undergoes 100% inspection, and a test report is provided with the goods. The production team holds certificates to work (welders hold special equipment operation certificates), and the standardized workshop ensures the consistency of mass production.
