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.
Claims9
A plastics injection molding machine, comprising:
- a heatable plasticizing cylinder having an inlet side for incoming plastic material and a machine drive for operating a screw in the plasticizing cylinder and for operating an injection mold for receiving the incoming plastic material from the plasticizing cylinder for making an injection molded article;
- and
- a heat transport system acting between the machine drive and the inlet side of the plasticizing cylinder for preheating the incoming plastic material with waste heat generated by the machine drive for recovery of energy.
An injection molding machine, comprising:
- an injection mold;
- an extruder having a plasticizing cylinder provided with an inlet for entry of plastic material into the plasticizing cylinder, and a screw contained in the plasticizing cylinder for moving the plastic material through the plasticizing cylinder for introduction into the injection mold as a molten mass;
- drive means operating the screw and operating the injection mold;
- and
- a heat transport system interacting with the drive means for transferring waste heat generated by the drive means for preheating the plastic material entering the plasticizing cylinder through the inlet.
