A method for centrifugally casting thermosetting plastics and the like, this method including the following steps of assembling and closing a casting mold having an upper portion and a lower portion; placing a prepared dividing hub onto and over a plurality of drive pins provided on a spinner carried by a stationary base, said dividing hub having a reservoir engaging a plurality of prepared closed casting molds onto and over a like number of nozzles, each of said nozzles extending radially from the sides of said dividing hub; placing and tightening a clamping means around the perimeter of the casting molds; pouring a pre-measured quantity of the thermosetting plastic into said reservoir in the dividing hub; moving a vacuum hood to the stationary base and with gasket means forming a vacuum chamber with said stationary base; evacuating the now closed vacuum chamber; forming and providing a conduit connecting an extreme tip of each of said nozzles with a bottom portion of the reservoir and then spinning the casting molds wherein the thermosetting plastic material flows from the reservoir through the connecting conduit and then into the casting molds; stopping the spinning casting molds; venting the vacuum chamber; moving the vacuum hood to an open condition; releasing and opening the clamping means; curing the thermosetting plastic within the casting molds at a station remote from the apparatus; disassembling the casting molds, and removing the cast items from the molds after curing.
