ABSTRACT:
A rotary molding apparatus is described, including a heating chamber, cooling chambers and supports for molds which melt and cast workpieces of plastic. The cooling chambers can be arranged circularly around the heating chamber which is disposed at the center, or the heating chamber can be movable such that an opening thereof can be selectively aligned to one of the cooling chambers. The molds can be moved via the supports from a cooling chamber to the heating chamber and back again. This apparatus optimizes component utilization and minimizes cycle times.
