Quality control:
(1) Machinery properties and chemical components testing after raw casting
(2) Hardness checking after heat treatment
(3) Dimensions testing after machining
(4) Quality control checks though all the following flow:
Drawings→ mould making →raw casting → sandblasting →rough machining or finish machining →surface treatment →product check→ packing →delivery strict
