As a core components manufacturer in high-tech fields such as semiconductor industry and biopharmaceutical industry, we are well aware of our responsibilities. The alloy composition is confirmed by inductively coupled spectrometer and carbon sulfur instrument, and the hidden crack is tested by Rotary Eddy current flaw detection, until XPS analysis and passivation layer test. PVE adheres to the inspection beyond the industry standard and make sure 100% traceability, all these are for living up to your trust .
