Our quality control system covers the entire production lifecycle. Every component undergoes rigorous inspection at multiple stages — from raw material verification (IQC), through in-process monitoring (IPQC), to final outgoing quality check (OQC). All measurements are recorded and traceable.
QC Workshop
Our quality control workshop is equipped with over 20 units of professional testing instruments, including Vickers hardness testers, Rockwell hardness testers, powder density testers, optical crack detectors, and more. Every batch of products undergoes rigorous inspection before shipment to ensure consistent quality and reliability.
