Our quality control begins from raw material, forging, heat treatment, semi-finished machining, final machining till assembly, each step is controlled strictly by our engineers, all of them have 10+ years of engineering experience and are specialized in metallurgy, forging, heat treatment, NDT, machining and testing respectively.
The outline of quality control process as follow
(bar, ingot, tube)
Metallographic test etc
(Close die forging)
(Open die forging)
Reduction ratio etc
Rough machining Heat treatment
(precipitation hardening, normalizing,
Mechanical properties, Impact test,
Metallographic test, Ultrasonic test,
Magnetic particle test, etc.
(CMM, projector, etc)
(induction harden, QPQ, nitriding, carburizing,
carbonitriding, Nickel plating, etc)
Thickness test etc
Load test etc.
