PreProduction: Raw materials are examined to ensure that they have reached customers' requirements. For any problem, the controller will submit a report to the QC supervisor.
Production Line: Based on random sampling technique, our QC members check a set of samples. If the defective products exceed the pre-assigned percentage of errors, the whole production line will be reviewed.
Finished Products: Our quality controller performs a visual check on every piece of finished product to make sure it qualifies.
