  • Publication number: 20140117573
    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: 8529239
    Abstract: A soap remnant molding assembly is provided for combining, heating and re-forming small soap remnants into full size soap bars. The assembly includes a housing having a bottom and an exterior wall defining an interior space of the housing. A tray is positioned in the interior space. A plurality of heating elements is positioned in the interior space around the tray. A power source is operationally coupled to the heating elements and a switch is operationally coupled between the heating elements and the power source. The switch selectively activates and deactivates the heating elements to heat and then cool the tray such that the soap remnants convert to a liquid and the liquid in the tray subsequently hardens into a single soap bar.

    Abstract: A system manufactures molded fatty acid based material products by forming a fatty acid based material paste and injecting the paste into a mold having internal cavities. The system includes a controller that regulates heat generated by a movable member in the barrel of an injection molding machine and a cooling jacket on the exterior of the barrel to enable nearly melted fatty acid material and nearly solid melted fatty acid material to mix within the barrel to form a paste that is ejected into a mold to form the products. The paste enables the products to form a skin that is less susceptible to shrinkage during cooling so the product is formed without voids that cause breakage or mar aesthetic appearances of the product.

    Abstract: A process for production of a heat-resistant hollow article made of a polylactic acid containing resin by using a mold which includes a female mold portion having a concavity, a male mold portion having a convexity and a stripper plate having an edge-forming part. The surface of the mold facing the cavity is heated to a temperature corresponding to a crystallization temperature of the polylactic acid containing resin. The male mold portion and the stripper plate are moved away from the female mold portion when a temperature T(° C.) of the resin detected by an infrared temperature sensor is in the range of T=(t+3.5)±1.5 (t(° C.) is the surface temperature of the mold). Gas is introduced between an inner surface of the hollow article and the male mold portion, and the hollow article is taken out of the mold by advancing the stripper plate toward the hollow article.
