All raw materials must undergo rigorous physical and chemical property tests and non-destructive testing before entering the production process to ensure that they meet production requirements.

Corresponding quality inspections will be carried out after each process to ensure that each intermediate product meets the design requirements.

All finished products are fully inspected to ensure that the product's dimensional accuracy, physical properties and appearance meet customer requirements.

Before packaging the product, we will conduct a final appearance and functional inspection to ensure that each product can be delivered to the customer safely and intact.
