The company has established a mature and effective quality management system and has obtained ISO9001, ISO14001, and IATF16949 certifications.

The APQP team designs products based on customer input and conducts a detailed risk analysis of the product design, including but not limited to DFMEA, FMA fault tree analysis, and other forms of output for design proposals and reviews. They also prepare executable operation specifications and quality control plans.

Systematic management processes are implemented to ensure that the content of control documents (control plans, FMEAs, drawings, etc.) specified in the work instructions are effectively implemented, including process parameters and operating methods.

For key processes/special characteristics, the planned requirements (control plans) are validated, control methods are determined based on validation or verification results, and are clearly defined in control plans/process documents.

Engineering changes (including product and process changes) are communicated to customers promptly, with details of the changes and reasons provided.

Product data is tested according to inspection specifications, recorded, and marked with status indicators (to be inspected, inspection passed, inspection failed, pending judgment). Statistics are conducted on incoming material acceptance, production process non-conformances, and post-sales non-conformances. Periodic analysis is conducted on product and process failures, reasons for failures, and the effectiveness of measures taken, and updates and improvements are made to special characteristics lists, FMEAs, control plans, and other documents. A traceability system is established for the produced products, with a traceability plan formulated to ensure the traceability of production dates, machinery, production lines, and suppliers and their batches of product components.

Purchased materials comply with the "Qualified Supplier List," and all purchased products or materials comply with applicable laws and regulations. Sample approval/PPAP approval of raw materials is completed before mass production, and supplier performance is monitored.

Information provided by customers (such as non-conformities, downtime, delivery issues, service problems, etc.) is analyzed for root causes, and improvement measures and measures to prevent recurrence are formulated. The relevant measures are implemented on the production site, and regular customer satisfaction evaluations, analyses, and reviews are conducted.
