Quality management is not only related to the self inspection, initial inspection and inspection of employees, but also related to the management of temperature, pressure, test equipment and production environment. Our quality management system supports the automatic collection, statistics and analysis of quality related data in the whole production process, and realizes the automatic quality monitoring of the production process. If the "weight" and "roundness" exceed the theoretical value, the system will give an alarm automatically to realize the unification of product quality, process control and batch traceability management.
