         2. Semi-perfect quality control management in the manufacturing process

2.1 During the production process, the quality inspector is responsible for the inspection and inspection of the semi-finished products in each process, and keeps a “daily inspection record” for traceability.

2.2 When unqualified, make a mark and record, and isolate it. Immediately notify the production manager to rework or repair.

4.1 The quality inspector shall make a timely inspection record for each inspection. The record is the main basis for judging and tracing the unqualified.
