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 the different volumes of furnaces, the order quantity can be very flexible.
3. Machining
CNC, lathing, drilling, milling, grinding, wire cutting, polishing
Technical requirements of our bushings
Dimensions, drawings, tolerance, surface finish, radius, as your demands.
1. High-temperature resistance
The strength keeps stable up to 800 and it can even be 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 has exceptional wear and galling resistance.
3. Corrosion resistance
This excellent 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 process. It has better strength than casting parts, better granule structure, and avoids the troubles caused by casting defects.
