Abstract
Apparatus for making injection molded polymeric articles, comprising a vibratory pneumatic cooling assembly adapted to dissipate thermal energy from the polymeric articles after they are ejected from the mold cavities through use of an oscillating perforated vibratory grid adapted to maintain the articles in relative motion while at least partially supporting them on a substantially uniform cushion of air. A method for employing the apparatus of the invention to substantially reduce the cycle time required for injection molding polymeric articles is also provided.
