Centrifugal Casting

Centrifugal casting, also can be referred as roto casting, is the process by which a mold is rotated rapidly about an axis as molten metal is introduced into the mold. The mold shape is cylindrical but the outside of the finished part can be round or a simple, symmetric shape. The interior of the centrifugal casting will always be hollow and rounded.

Centrifugal casting is well known for the high quality of the results attainable and is particularly for precise control of their metallurgy and crystal structure. As compared to the other casting techniques, centrifugal casting is chief choice to be used to make stock materials in standard sizes for further machining, rather than shaped parts tailored to a particular end-use. Gun barrels, rotor end rings, and pipes are made by the method of centrifugal casting. Centrifugal casting equipment can be quite expensive, but the molds tend to last a long time and are good for large production runs. The metals recommended for centrifugal casting include iron, steel, stainless steel, and alloys of aluminum, copper, and nickel.
