Title: Method and apparatus for applying a ring of material to a centrifugal casting mold
IPC: B22D13/10
Filed: 1984-09-21
Abstract: Establishing a ring of particulate material on the internal surface of a centrifugal casting mold (1) when the ring, which can be either an end ring or an internal ring, has axial dimensions small in comparison to the length of the mold. The ring is established by confining a quantity of the particulate material in a cavity (18) of a tool (3), inserting the cavity into the mold, rotating the mold and the cavity at substantially the same rate adequate to apply substantial centrifugal force to the particulate material in the cavity, and opening the cavity to release the particulate material while continuing to rotate the mold and the cavity.

If the particulate material contains a binder low speed rotation of the mould is used during establishing the ring. Preferably, however, the particulate material is binderless and the mould is rotated sufficiently rapidly both to retain and densify the material whereby it may be contoured as the tool is withdrawn to complete formation of the ring.
