Abstract
A centrifugal casting method for producing a casting of a metallic material comprises positioning a rotatable assembly comprising a plurality of gates and a plurality of cavities positioned about a sprue chamber. The plurality of gates and the plurality of cavities are positioned to receive molten metallic material from the sprue chamber in a general direction of centrifugal force. Each of the plurality of gates is coupled to one of the plurality of cavities, and at least two of the plurality of cavities are stacked. The method further comprises rotating the rotatable assembly. The method further comprises delivering a supply of molten metallic material to the sprue chamber.
Claims24
A method of producing a casting of a metallic material, the method comprising:
- positioning a rotatable assembly comprising a plurality of gates and a plurality of cavities disposed about a sprue chamber such that the plurality of gates and the plurality of cavities are positioned to receive molten metallic material from the sprue chamber in a general direction of centrifugal force as the rotatable assembly rotates, wherein each of the plurality of gates is coupled to one of the plurality of cavities, and wherein at least two of the plurality of cavities are stacked;
- rotating the rotatable assembly;
- and
- delivering a molten metallic material to the sprue chamber.
A method of assembling a centrifugal casting apparatus, the method comprising:
- positioning a wedge on a rotatable axis;
- positioning at least two molds into sealing engagement with the wedge, wherein each of the at least two molds comprises a front face and defines at least two cavities extending from the front face into the mold;
- and
- defining a sprue chamber structured to receive molten material, wherein at least a portion of the sprue chamber is defined by at least a portion of the front faces of the at least two molds.
