The APQP management process is used in the product development phase, from planning and finalizing the project, product design and development verification, process design and development verification, product and process validation, feedback, assessment, and corrective action. In the design and development process, DFMEA is used to fully analyze the failure modes of the design to minimize possible design defects. The laboratory has various types of test equipment to test the performance of various materials and products. In particular, the newly introduced MTS spherical joint test system and MTS four-axis test platform represent the industry's leading international standards.

In process control, people, machines, materials, methods, rings, tests and other factors are strictly controlled. The company regularly trains its employees in technology, quality awareness, etc. to continuously improve the quality of their employees. In addition to the fact that employees perform equipment inspections before daily operations, they must also perform secondary and tertiary maintenance in accordance with the “Annual Maintenance Plan for Equipment”. The materials in the process are identified to ensure the traceability of the material identification and verification status. Vigorously implement "5S" management to maintain a good production order, reasonably equipped with station equipment, and ensure the smooth production channels. Use QC's seven techniques to continuously improve product quality. The QC team was set up in each production workshop to conduct statistical analysis on the bad phenomena that occurred. The 8D method is applied to the quality anomaly so that the problem can be completely solved. Use SPC statistical techniques to analyze and improve process capabilities. Strictly control the first self-test in production. Professionals perform regular checks on various types of gauges to ensure the accuracy of the measurements.

All suppliers must be reviewed by the technical department and the quality control department before they can become the company's official suppliers, and conduct annual audits once a year. Track non-conformances during the audit until the improvement is completed. According to the quality of the suppliers, they are divided into A, B, and C levels. The qualified rate of suppliers' incoming materials is analyzed statistically, and the key items are specifically tutored.

At present, the company's quality system has gradually improved, but quality control never ends, we will continue to improve the company's quality. Customer satisfaction is always our persistent pursuit.
