RAW MATERIAL QC

Each batch of material must pass through the vibrating screen, strictly control the possible uneven particles or impurities, make sure that the particle size of each batch of materials is uniform, to get the fine material every time.

BLANKS QC

We make sample piece for each batch of raw material, after monitoring and analysis of the sample piece, we obtained various performance parameters of this batch of raw materials, includes its density, hardness, bending strength, porosity, metallographic structure, magnetic saturation, etc., and the corresponding data will be recorded, be numbered and be archived, the retroactive period is 18 months.

SEMI-FINISHED QC

Inspecting the hardness of the steel shank after welding and weld strength, especially in the development of more advanced welding technology, decision based on data not just speculation.

FINISHED QC

The tooth shape structure and angle of carbide tools will be checked by the quadratic element image measuring instrument, make sure the edge of tooth is sharp without visibly jaggy.
