Abstract
A process for injection molding of molded parts made from thermoplastic plastic material having at least one cavity, which includes: a) injection of thermoplastic plastic melt from an injection unit along a melt flow path into the cavity of an injection-molding die; b) injection of a fluid into the still molten plastic material, so that the latter is pressed against the walls of the cavity; c) allowing the plastic material to cool until the latter forms the molded part in self-supporting manner; and d) releasing the molded part from the cavity of the injection-molding die.
