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

    Different volume of furnaces, the order quantity can be very flexible.

3. Machining

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

Product Features

1. High temperature resistance

    The strength keeps stable up to 800 and it can even momentarily used at 1200.

2. Wear resistance

    Due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a

    CoCr alloy matrix, it has exceptional wear and galling resistance.

3. Corrosion resistance

    This exellent and lovely property allows this kind of material parts to be used in oil&gas, slurry,

    acid liquid and any other mediums.

4. Production process

    Powder metallurgy pocess. It has better strength than casting parts, better granule structure and

    avoiding the troubles caused by casting defects.
