Abstract
A system and method are provided for molding a solid plastic part utilizing a mold having at least a core portion and a cavity portion which define a mold cavity. With the mold closed, pressurized steam is circulated through the mold cavity to heat the interior surface of the mold cavity. Once the mold cavity surface has reached the desired temperature, the pressurized steam is vented. When the condensate has been sufficiently removed, a fluid plastic is injected into the mold to the mold cavity. A pressurized fluid is introduced in the mold through a port on the mold core portion to bias the part being formed into engagement with the mold cavity. Once the part is cooled sufficiently to be stable, the mold is opened and the part is removed.
