QUALITY CONTROL
Quality:Insist on Improvement,Strive for CZPT With the development of equipment manufacturing indurstry,customer never satirsfy with the current quality of CZPT products,on the contrary,wcreate the value of quality.
Quality policy:to enhance the overall level in the field of CZPT transmission  
Quality View:Continuous Improvement , pursuit of excellence
Quality Philosophy:Quality creates value

3. Incoming Quality Control
To establish the AQL acceptable level of incoming material control, to provide the material for the whole inspection, sampling, immunity. On the acceptance of qualified products to warehousing, substandard goods to take return, check, rework, rework inspection; responsible for tracking bad, to monitor the supplier to take corrective measures to prevent recurrence.

4. Process Quality Control
The manufacturing site of the first examination, inspection and final inspection, sampling according to the requirements of some projects, judging the quality change trend; found abnormal phenomenon of manufacturing, and supervise the production department to improve, eliminate the abnormal phenomenon or state

5. FQC(Final QC)
After the manufacturing department will complete the product, stand in the CZPT er’s position on the finished product quality verification, in order to ensure the quality of CZPT er expectations and needs.

6. OQC(Outgoing QC)
After the product sample inspection to determine the qualified, allowing storage, but when the finished product from the warehouse before the formal delivery of the goods, there is a check, this is called the shipment inspection.Check content:In the warehouse storage and transfer status to confirm, while confirming the delivery of the product is a product inspection to determine the qualified
