Detection process

1. Purchased parts / cooperation parts detection, qualified use, unqualified returns

2. Purchase raw materials, qualified warehouse, unqualified returns

3.The raw material is processed, and the test is carried out by punching / tapping / riveting / pressure injection, then the surface treatment is carried out after the inspection is qualified

4. Before the parts are assembled, they are tested for pressure resistance and high-temperature resistance, rework if unqualified

5. Before shipment, the factory inspection is carried out, and the performance is tested.
