Why Can We Always Ensure Excellent Quality

Quality Control

1. There are strict control procedures for incoming materials, and each incoming material can be traced back to the source;

2. In the production process, the quality inspector randomly checks, the unqualified products will be directly smashed, and the quality inspector is independent of the production department, so as to maintain neutrality;

3. Re-inspect the finished product before putting it into the box;

4. Random check before shipment.
