Components for transmission system. The main material is powder metallurgy.

The process flows as follows:

1. Pressing(the pressing machine is controled by computer to ensure the quality is stable and high precision)

2. Sinter

3. Sizing& Re- Pressing

4. Finishing

5. After- Treatment(Including oil dip, Stream treatment and so on, In order to improving the surface hardness, Cleanliness and the oiliness of the products)

6. Testing (air stream test, 3D test, Strength test, Hardness test, Run- Out test)
