We currently have a coordinate measuring machine (CMM), video measuring machine (VMM), surface roughness tester, profilometer, etc. and other inspection equipment and gauges assisting in control plans. The inspection process includes initial sample inspection, incoming inspection, in-process inspection, final inspection, outgoing inspection and full article inspection. We carry out product dimensions and geometric measurements by inspection equipment to confirm that product quality meets customer requirements. Our quality policy "quality first, customer satisfaction" is thoroughly implemented.
