Visual Inspection
Each raw material has a 3.0 certificate and all the materials will be stocked and marked by a color code in warehouse.
Dimension Inspection
3D Coordinate Measurement Machine can help us to check the diemsions of the parts precisely
Chemical Analysis & PMI inspection
The spectrometer accurately measures the content composition of the material to ensure the reliability of the raw material.
Mechanical Examination
impact testing
Semi-automatic impact testing machine can test the impact resistance of the material under dynamic load
