In manufacturing and QC, TOPGRREN tracks product number, specification, quantity from the beginning of manufacturing as well as calibration and recording, and assures consistency with the quantity and specification on customer order.

　　In raw material monitoring, when raw material quality is poor, immediately reject it and make up with the same quality material. If defect product is found during manufacturing, immediately stop production and trace back to prevent from going to the next stage.
