Quality Control
1)Checking the raw material after they reach our factory------- Incoming quality control ( IQC)
2) Checking the details before the production line operated
3) Have full inspection and routing inspection during mass production---In process quality control(IPQC)
4) Checking the goods after they are finished---- Final quality control(FQC)
5) Checking the goods after they are finished-----Outgoing quality control(OQC)
