Based on the concept of quality priority, the company carries out reliability verification on materials with high recognition on the market, and then puts it into production and batch use. Established a complete set of supplier access processes. The management of daily suppliers is strictly prohibited and minimizes the possibility of quality problems caused by materials. The materials provided by the supplier are required to be traced to the batch, and the batches in the production are recorded in strict accordance with the requirements of ISO9000 and TS16949 to ensure the traceability of the materials used in the factory.


In the production process, the work order follows the batch material turnover, and each process has recorded and received signatures, and the quantity and quality statistics are strengthened to effectively avoid the mixing problem.
