Quality system:
1. Our factory has a very intrinsic quality inspection system for each program. QC operators inspect the semi-finished products as QC flow chart and FMEA in each production process to ensure that each part is eligible for the next process.
2. When the first batch of finished products is completed, we will carry out tests on the products in the laboratory, as OEM standards and in line with national standards, and then package them into the warehouse.
3. For any quality issues, we will provide corrections at the first time to ensure that the same quality issues do not occur.
4. The quality management system has passed the ISO9001-2018 certificate.
