摘要： A method of fabricating a foamed, injection-molded component is provided. The method includes the step of plasticizing pellets including a first polymeric material and a second polymeric material within an injection barrel to form an injection material. The first polymeric material defines a first phase of the injection material and the second polymeric material defines a second phase of the injection material. The first and second phases of the injection material are immiscible. The injection material is injected into a mold to fabricate the foamed injection-molded component having microscale, microcellular voids. Upon tensile loading, submicron, secondary phase cavities are formed in the injection-molded component, resulting in improved ductility and toughness.

摘要： In a method of microcellular injection molding, a polymer and a supercritical fluid are processed. A condition of processing the polymer and/or the supercritical fluid is adjusted to control a weight of a plastic part and/or a surface characteristic of a plastic part produced. In another method of producing a plastic part using microcellular injection molding, a polymer is heated and melted and a supercritical fluid is added thereto. The resulting mix is a single-phase polymer-gas solution comprising the polymer and the supercritical fluid. The polymer and/or the supercritical fluid are adjusted to control the weight of the plastic part and/or a surface characteristic of the plastic part. Once adjusted, the melted polymer with the supercritical fluid is injected into a mold. Upon injecting the melted polymer and supercritical fluid, a pressure drop causes the supercritical fluid to nucleate in the melted polymer, thereby causing nucleation of bubbles.

摘要： To provide an expansion injection molding process, which is freed from the occurrence of swirl marks on the surface of a molded article and by which foamed injection moldings having good appearance can be produced in a short molding cycle and at a low cost; and a mold for expansion injection molding.A movable mold 2 is moved toward a fixed mold 1, whereby a sealing member 6 set on at least one of a pair of facing surfaces of the mold 1 and mold 2 in the outside of a cavity is brought into contact with the other of the facing surfaces or a sealing member 6 set thereon to make the cavity 3 gas-sealed state. While keeping the gas-sealed state, the movable mold 2 is further moved toward the fixed mold 1 with the sealing member 6 compressed, whereby the volume of the cavity 3 is decreased to enhance the pressure in the cavity 3 to a level exceeding the atmospheric pressure. Then, a thermoplastic resin is injected into the cavity 3 of an enhanced pressure.
