The production process of our bushings

1. Powder metallurgy process

     A. Better metallurgical structure, better strength

     B. Various types of automatic pressing machines from 3 tons to 630 tons. The ordered profiles

          can be very flexible.

2. Investment casting process

    With different furnace volumes, the order quantity can be very flexible.

3. Machining

    CNC, lathing, drilling, milling, grinding, wire cutting, polishing
