1. The quality inspection department is responsible for the "quality inspection, quality feedback, and quality statistical analysis of the entire production process from outsourced raw materials to outsourced parts, rough semi-finished products, and finished products leaving the factory."

2. Strictly implement the "three presses" (according to drawings, process documents, and operating procedures) and the "three no-nos" (unqualified products are not allowed to be put into the warehouse, unqualified products from the previous process are not allowed to be transferred to the next process, and unqualified products are not allowed to be transferred to the next process) factory). Ensure that products adopt correct inspection methods and judgment standards in various processes and procedures so that products meet quality requirements.

3. Inspectors should strengthen inspections and do a good job of "self-inspection, first inspection, and inspection." If they find substandard products, they must point them out at any time to correct quality problems. Operators must conduct self-inspections. If the situation is more serious, they must report to the leader.

4. Implement product self-inspection and mutual inspection systems, and establish the concept that the next process is the customer. The quality inspector has the right to stop and report to the leader any team or individual who does not accept inspection, intentionally transfers to the next process without inspection or fails self-inspection. Identify responsibilities and implement financial penalties for safety and quality accidents that cause economic losses.

5. Completion inspection: Final inspection of the process, after removing burrs, iron chips and oil stains from the parts. The inspector conducts random inspections on the batch of products and makes a status mark. If unqualified products are found during sampling inspection, the sampling should be doubled for re-inspection. If they are unqualified, they will be returned to the workshop, self-inspected, and re-submitted for inspection. Unqualified products will not leave the factory.
