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.
