Centrifugal casting technology
Centrifugal casting or rotocasting is a casting technique that is typically used to cast thin-walled cylinders. It is used to cast steel, copper and others. It is noted for the high quality of the results attainable, particularly for precise control of their metallurgy and crystal structure.
The centrifugal casting products BACSOONT are manufacturing include centrifugal casting copper bushing, centrifugal high manganese steel bushing, centrifugal casting steel bushing, centrifugal casting steel pipe and others, the OD can meet dimensions of 20 mm to 2000 mm.
