Centrifugal casting apparatus and method

摘要

A centrifugal casting apparatus includes a rotatable assembly to rotate about a rotation axis. The rotatable assembly includes a sprue chamber positioned about the rotation axis and is shaped to receive a supply of molten material. A first gate and a second gate are positioned to receive molten material from the sprue chamber in a general direction of centrifugal force. A first cavity and a second cavity are stacked and are respectively positioned to receive molten material from the first gate and the second gate in the general direction of centrifugal force.

1. A centrifugal casting apparatus comprising:
a rotatable assembly configured to rotate about a rotation axis, wherein the rotatable assembly comprises:
a sprue chamber positioned about the rotation axis and structured to receive a supply of molten material;a first gate positioned to receive molten material from the sprue chamber in a general direction of centrifugal force;a second gate positioned to receive molten material from the sprue chamber in the general direction of centrifugal force;a first cavity positioned to receive molten material from the first gate in the general direction of centrifugal force, wherein the first gate comprises a volume greater than a volume of an equal adjacent length of the first cavity; anda second cavity positioned to receive molten material from the second gate in the general direction of centrifugal force; wherein the first cavity and the second cavity are stacked.
