Abstract
A plastics injection molding machine includes a heatable plasticizing cylinder having an inlet side for incoming plastic material and a machine drive, and an injection mold receiving the plastic material from the plasticizing cylinder for making an injection molded article. Acting between the machine drive and the inlet side of the plasticizing cylinder is a heat transport system for preheating the incoming plastic material with waste heat generated by the machine drive to thereby realize a recovery of energy.
