ABSTRACT:
An apparatus for serially molding articles from a plastic resin material includes an extruder having an output for producing a stream of plasticized resin material. A circular array of molds is arranged about a central area and a runner system coupled between the extruder output and the circular array of molds maintains the stream of plasticized resin material at a temperature suitable for molding. A valve is connected between the runner system and an input leading to an accumulator chamber of each mold of the circular array for sequentially directing the plasticized resin into each of the molds to form a molded article therein. A molded article extractor sequentially removes the molded article from each of the molds, and a molded article handling apparatus coupled to the molded article extractor arranges the molded articles in a series for removal through the central area.
