During and after production all products undergo a systematically testing including chemical composition and mechanical properties test, measurement test of all dimensions after casting, ultra sonic test, magnetic particle test, surface roughness test and dye penetrant inspection for critical parts, measurement test of all dimensions after machining, hardness test, assembly and interchange ability test, and visual inspection for all parts.
Valtech has the latest instruments to conduct the following non destructive and positive metal identification tests: Dye penetrate test; magnetic particle test; ultra sonic test; PMI and X-ray.
It also carries out dye penetrant and magnetic particle tests on metal tubing which are used to make fasteners and other components.
