Beschreibung
Zusammenfassung:	An apparatus and method of producing molded plastic products provides the molded plastic products of high accuracy and with short molding cycle. A resin is placed in a cavity of a mold for forming the product therein. When the resin cools in the cavity of the mold to a temperature lower than the softening temperature of the resin, air gaps are forcibly formed between the resin and the plural cavity pieces, by slidably moving the cavity pieces so as to part the cavity pieces from the resin. The mechanism for forming the air gaps is included as part of the apparatus, and the method includes the step of forceably forming the air gaps.
