The present invention relates to an apparatus and process for injection molding polymer articles that reduces deposition of additives on the apparatus. Specifically, pressurizing of the mold cavity with a pressurized gas reduces the deposition of low molecular weight additives on the apparatus. Embodiments of the invention also include an apparatus for injection molding polymer articles comprising at least one pressurized gas inlet for introducing a pressurized gas into the mold cavity.

Pressurized tooling for injection molding and method of using

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.

A redistributing device for use with melt flow exhibiting boundary layer flow and centralized flow comprises a body including a melt flow inlet end and a plurality of melt flow outlets. A first flow diverter is included for distributing at least the boundary layer flow among the plurality of the melt flow outlets. A second flow diverter is included for distributing at least the centralized flow among the plurality of melt flow outlets.
