03.
Process advantage
After years of accumulated production, research and development experience, Yonggao has achieved the best production process standards. The technical department will first carry out trial production according to technical standards. Then when the first product is inspected by the quality control department, the workshop production process standards will be locked. Any adjustments need to be authorized. Workers have no right to adjust the production process and time, which ensures the stability of production.

The company's quality control process mainly includes first article inspection, process inspection, packaging inspection, and finished product inspection The first inspection is carried out by production employees, machine repairers, and quality inspectors to test and test the trial production products, and then start mass production after passing the test.
Process inspections are randomly inspected by process inspectors every four hours to supervise the quality of bulk goods The packaging inspection is randomly selected by process inspectors to supervise the quality of the goods and packaging during the packaging process. Finished product inspection includes: Product performance inspection is strictly based on the standards of each market.
