  • Patent number: 8622726
    Abstract: 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.

  • Patent number: 8550800
    Abstract: It is an object to prevent dies from interfering with each other when the dies are closed and effectively prevent overshoot of cavity temperature while efficiently performing heating of the dies. In an injection molding machine for two-material molding including two sets of a first injecting unit and a second injecting unit that respectively plasticize different resin materials and inject and fill the resin materials, prior to performing injection molding on the first injecting unit side on a secondary side, after injection molding on the second injecting unit side on a primary side, heating of the dies is started before 180-degree rotation of a rotary die plate is completed. After the start of heating, until the 180-degree rotation of the rotary die plate is completed, i.e., die closing is performed, die temperatures are maintained within a temperature range set higher than die temperatures during the heating start and lower than die temperatures during injection.
