Quality Assurance

Quality Assurance

We passed the ISO9001 quality management system certification in 2001, ISO/TS16949 certification in 2004, and IATF16949 certification in 2018. We have high-precision testing equipment: three-coordinate measuring instrument, profile measuring instrument, roundness measuring instrument, 3D scanner, spectrum analyzer, X-ray flaw detector, audio detector, etc., to meet the quality testing requirements. Product and production process design uses the experimental design (DOE) method to select the best product and process parameters; in the production process we use the statistical process control (SPC) method to stabilize the production process and continuously improve the process capability (Cpk).
