ABSTRACT:
A method and apparatus for compression molding plastic articles include a plurality of tools mounted in opposed pairs with the tools of each pair including opposed first and second actuators that define a mold cavity in which a charge of plastic is compression molded. The tooling is preferably carried by a rotary turret so that first and second actuators of each tooling pair are moveable relative to each other between an open position permitting formed articles to be removed from the tooling and to receive fresh charges of plastic, and a closed position to compression mold the charges of plastic.
