Methods of making centrifugally cast parts

摘要

This invention provides the method of centrifugal casting consisting of the steps of: adding a polymeric material to a centrifugal apparatus; centrifuging said polymeric material until said polymeric material is cast; removing said cast polymeric material from said centrifugal apparatus; and mounting said cast polymeric material to an outside surface of a support, whereby the air interface side of said cast polymeric material is furthest from the outside surface of the support.
