During the production of bluetooth blue light glasses, Leeyongin Safety Tech Limited divides the quality control process into four inspection stages. 1. We check all incoming raw materials before usage. 2. We perform inspections during the manufacturing process and all manufacturing data are recorded for future reference. 3. We check the finished product according to the quality standards. 4. Our QC team will randomly check in the warehouse before shipment.
