Abstract

An apparatus for high-throughput rotational molding processes includes a multiplex mold having an upper mold, a lower mold and a plurality of orifices, where the upper mold is configured to be reversibly sealable with the lower mold and the plurality of orifices define a corresponding plurality of molding chambers; and a multiplex swing arm including at least one swing arm lever and a plurality of swing arms, where the plurality of swing arms corresponds to the plurality of orifices. A rotational molding process includes steps of raising the upper mold off of the lower mold; and receiving the multiplex swing arm in the lower mold, where the plurality of swing arms corresponds to the plurality of orifices, the multiplex swing arm being rotatable between a molding position and a de-molding position.
