  • Patent number: 8404168
    Abstract: A process for producing a thermoplastic resin molded product, comprising: a placement step of placing a thermoplastic resin particle composition 6A into a cavity 22 of a rubber die 2 made of a rubber material; a particle heating step of irradiating the thermoplastic resin particle composition 6A in the cavity 22 with electromagnetic waves having wavelengths ranging from 0.78 to 2 ?m through the rubber die 2, thereby heating to melt the thermoplastic resin particle composition 6A; a filling step of filling a thermoplastic resin 6 in a molten state into a space 220 left in the cavity 22; and a cooling step of cooling a thermoplastic resin 6 in the cavity 22 thereby obtaining a thermoplastic resin molded product.

  • Patent number: 8293165
    Abstract: A resin forming method and a resin forming apparatus for obtaining a resin formed product, by filling a cavity of a rubber-made mold with a thermoplastic resin, and cooling the thermoplastic resin. When filling the cavity with the thermoplastic resin, an electromagnetic wave generator is used, and electromagnetic waves having an intensity peak in a wavelength region of 0.78 to 2 ?m are irradiated to the thermoplastic resin from the surface of the mold, and thereby the thermoplastic resin is heated selectively from the mold. The thermoplastic resin is an ABS resin which either a noncrystalline thermoplastic resin, or is a rubber modified thermoplastic resin.

  • Publication number: 20110304079
    Abstract: A rubber mold for molding a resin 2 is provided with a cavity 213 for filling therein a thermoplastic resin in a molten state by applying pressure. The rubber mold 2 includes a core mold 21 made of a rubber material and provided with the cavity 213 and a base mold 22 made of a rubber material and having such a shape that the core mold 21 is to be placed therein. The core mold 21 is formed by combining a pair of split mold parts 211 which is divided on splitting surfaces 212 for opening the cavity 213. The base mold 22 has a bottom part 221 and a pair of first side parts 222 formed on two opposite sides in a direction in which the plurality of split mold parts are aligned with each other.

  • Publication number: 20110163481
    Abstract: The present invention presents a resin forming method and a resin forming apparatus 1 for obtaining a resin formed product, by filling a cavity 21 of a rubber-made mold 2 with a thermoplastic resin 3, and cooling this thermoplastic resin 3. When filling the cavity 21 with the thermoplastic resin 3, electromagnetic wave generating means 4 is used, and electromagnetic waves having an intensity peak in a wavelength region of 0.78 to 2 ?m are irradiated to the thermoplastic resin 3 from the surface of the mold 2, and thereby the thermoplastic resin 3 is heated selectively from the mold 2. The thermoplastic resin 3 is an ABS resin which either a noncrystalline thermoplastic resin, or is a rubber modified thermoplastic resin.
