FACILITIES

At Tech-Vina, quality control is the most important step in the entire production process. We apply the 5-step quality control process: 
- QC of materials at supplier's production facility
- QC of input materials at Tech-Vina factories
- QC of semi-finished products during production
- QC of finished products 
- QC of products before delivered to customers.
All samples during quality control are kept for at least 2 years.
