Abstract: While steam is supplied to flow channels to heat inner cavity surfaces to a temperature equal to or higher than the heat distortion temperature of a molding resin, the resin mixed with a supercritical fluid is injected from an injection molding machine into a mold cavity. When the injection of a predetermined quantity of the resin is completed, the supply of the steam to the flow channels is stopped, and cooling water starts to be supplied to the flow channels. The inner cavity surfaces are thus quickly switched from a heated state to a cooled state, cooling and solidifying the resin into a molded product of good appearance which is free of broken cell marks on its surface.

Abstract: The method of making polystyrene foam for foam products which includes utilizing atmospheric gases as the blowing agents or preferably mixing one or more of these gases and a blending agent which is non-volatile at the extrusion temperatures, introducing the mixture to a molten thermoplastic polystyrene resin containing nucleating agents such as sodium bicarbonate and citric acid and extruding the thermoplastic in the form of a foam. The resultant foam has substantially no residual blowing agent, is dimensionally stable at ambient temperatures and when used with a non-volatile blending agent can be made with small amounts of blowing agent permitting cooling of the melt without high loading on the extruder. The foam may be coextruded with one or more layers of thermoplastic film so that the resultant product is adapted for use for plates, cups, food containers or packaging and for labels for containers such as glass and plastic containers and for labels that are shrunk in place on a container.
