Inspection
Quality Control Philosophy: "Zero-defect Delivery, Full-cycle Assurance"  

Our Strengths – Powering Your Trust 
Strict Implementation of ISO-9001 Quality Management System
From raw material procurement to finished product delivery, we have established multi-level quality control checkpoints, ensuring full-process traceability.

Professional QC Team
We have a dedicated 10-member quality control team. With years of experience in the mechanical industry, our QC personnel are proficient in various testing methods. They regularly participate in skill training and quality improvement programs to continuously enhance quality awareness.

Precision Testing Equipment
Our temperature-controlled modern inspection lab is equipped with high-precision testing devices such as CMMs (coordinate measuring machines), optical comparators, hardness testers, surface roughness testers, and various gauges. We conduct rigorous inspections on key metrics like dimensional accuracy, tooth profile precision, surface quality, heat treatment, and hardness of sprockets.

Stringent Inspection Process
We enforce a three-tier inspection system: incoming material inspection, in-process inspection, and final outgoing inspection, supplemented by a dedicated sampling mechanism to eliminate batch defects. Critical processes—such as inner bore, keyway, and tooth profile—are assigned dedicated inspectors for specialized checks.
