Centrifugal Casting
The inertial forces of rotation or spinning are used to distribute the molten metal into the mold cavity or cavities in the centrifugal casting processes, a category that includes true centrifugal casting, semicentrifugal casting, and centrifuging.
True centrifugal casting Dry-sand, graphite, or metal mold is rotated about either a horizontal or vertical axis at speeds of 300 to 3000 rpm. As the molten metal is introduced, it is flung to the surface of the mold, where it solidifies into some form of hollow product
