We officially passed the ISO9001 quality management system certification in 2012, and further strengthened the quality management process operation. To ensure product quality, we set up the incoming inspection (IQC) and the three-process inspection system (IPQC first piece inspection, Process inspection, final inspection).

　　No bad production, no bad transmission, no bad outflow is our attitude towards quality. During the process circulation, we conduct process inspection (FQC) on different batches of products produced by the same process and the same machine to prevent Unqualified products flow into the next process.

　　In the inspection of finished products, we carry out outgoing inspection of products by referring to the original drawings of customers and strictly implement the inspection standards to ensure that the inspected materials meet the drawing standards and use demand of customers.
