Centrifugal casting method

摘要

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.

1. 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, wherein each of the plurality of gates is positioned and dimensioned to receive a volume of molten metallic material greater than a volume of an adjacent equal length of the cavity to which the gate is coupled, 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.
