摘要： A centrifugal casting apparatus is provided with means for supporting an article in a predetermined position with respect to a mold pattern in the casting apparatus whereby the article will be imbedded in the centrifugally cast body; counterweights are provided within the casting apparatus for compensating for the buoyancy of an article being imbedded where such article has a specific gravity that is less than the casting material.

摘要： A method and apparatus for the centrifugal casting of articles having non-uniform mass distributions with respect to an axis of rotation; the method comprises the steps of forming a sand mold in a cylindrical centrifuge, providing cavities in the sand mold adjacent the portions of the mold surface corresponding to that portion of the article to be formed which will have a reduced mass content with respect to the portion of the article formed on the opposite side of the axis of rotation of the centrifuge; conduits connect the respective cavities to the interior of the centrifuge so that casting material introduced into the mold may be fed into the respective cavities; the cross-sectional area of the conduits is chosen to meter the feeding of casting material into the cavities so that when the centrifuge is rotated the article being formed will be maintained in rotational equilibrium with respect to its axis of rotation.
