Testing four steps to ensure product quality with customers?
Step 1: Test for the raw materials.
Reject the unqualified raw materials directly.
Step 2: Test during production.
Test the Semi-finished products.
Strictly follow the production process and production plan to avoid inferior products due to lack of production process.
Step 3: Test after the goods are finished.
All finished goods are inspected and unqualified products must be re-produced.
Step 4: Test before shipment.
Re-inspect the goods before shipment to ensure that the goods delivered to the customer are high quality.
