The product quality inspection of our company is based on the manufacturing course of the products, including raw materials inspection when purchasing, semi-finished products inspection control, and the final inspection of the finished products. The raw materials inspection must be finished within 24 hours after purchasing, issuing a "detecting and testing report". Only after the qualified test, are the materials allowed to be stored in the warehouse; otherwise the raw materials will not be accepted or be part of the production procedure.
