a thermoplastic injection molding system and method of use is described for molding parts from heated plastics and other organic resins . the machine uses heat sources located along the barrel to heat the source material while an auger screw transports the source material in the barrel . this transport step does not shear the source material , nor does it use friction to produce the heat necessary to melt the source material . the material becomes substantially liquid or melted during the heating process , and the melted material is forced , by the auger screw , into a chamber whereupon a plunger , situated concentrically with the auger screw , injects the material from the chamber into a mold . sensors located along the barrel and in the chamber ensure consistency between mold cycles . the controller dynamically adjusts the injection molding process to achieve more consistent and reliable molded parts .
