HOME >> QUALITY CONTROL
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.

QUALITY CONTROL

——

The outline of quality control process as follow
​

Hardness test

Thickness test etc


Assembly
Pressure test
Load test etc.​
Rough machining Heat treatment
(precipitation hardening, normalizing,
quenching+temper, etc)
Mechanical properties, Impact test,
Metallographic test, Ultrasonic test,
Magnetic particle test, etc.
Raw material
(bar, ingot, tube)
EF+LF+VD/VOD+(ESR/VAR)
Spectra test
Metallographic test etc
Forging
(Close die forging)
(Open die forging)
​Forging temperature
Reduction ratio etc
Surface treatment
(induction harden, QPQ, nitriding, carburizing,
carbonitriding, Nickel plating, etc)
Dimensional inspection
(CMM, projector, etc)
Semi-finished machining
final machining
