Our quality inspection tools substantially cover the normal and special inspection as follows:
Material control- normal inspection items.
● Spectrometer: To inspect the chemical elements at 3 stages-incoming inspection, melting inspection and pouring inspection
● Metallurgical Microscope: To check the metallographic structure and morphology.
● Hardness tester: To check the hardness of test bar and product body
● Tensile strength test machine: To inspect the strength and elongation of the material
Inner defects control – special inspection items.
● Cutting inspection: Normally do at sample period. Will do if request in mass production.
● Ultrasonic to check the inner porosity. Will do if request.
● Magnetic particle test: To check the surface crack. Will do if request.
●X-ray test to check the inner defects. Subcontracted, will do if request.
Dimension and surface control:
● Calipers for normal raw parts dimension inspection. Sample inspect and spot inspect during production.
● Special gauge made for important dimension: 100% inspect
● CMM: For precision machined parts inspection. Sample and shifts inspection.
● Scanning inspection: subcontracted, will do if request.
All these tools are either applied in the production or after the production to ensure a safe process and safe result.
