  • Manufacture of forged components
    Patent number: 5671533
    Abstract: A method and apparatus for centrifugal casting a blank separable into a plurality of preforms having a required configuration for forging to a finished component. Individual molds are symmetrically located around the axis of rotation of a casting table and have mold cavities that are filled by molten alloy under the centrifugal force created by rapidly rotating the table. Alternatively, a cylindrical mold is centered on the axis of rotation and the centrifugal force created by rapidly rotating the table causes the molten alloy to fill cavities in the wall of the mold. Centrifugal forces of at least 20 g may be employed.
