  • Resin molding machine
    Patent number: 9738014
    Abstract: The compact resin molding machine is capable of efficiently performing a sequence of molding actions from feeding a work and resin to accommodating the molded work. The resin molding machine comprises: a work conveying mechanism including a robot, which has a robot hand for holding the work and which is capable of rotating and linearly moving; a work feeding section for feeding the work; a resin feeding section for feeding the resin; a press section including a molding die set, in which the work is resin-molded; a work accommodating section for accommodating the molded work; and a control section controlling the entire resin molding machine. The work feeding section, the resin feeding section, the press section and the work accommodating section are located to enclose a moving area of the robot of the work conveying mechanism.

  • Laminated structure for interior finishing materials, and method of production thereof
    Patent number: 4721643
    Abstract: A laminated structure comprising a laminated foamed sheet material composed of two cured foamed sheets each comprising a propylene-type polymer and an ethylene-type polymer and being laminated to each other through a substantially non-foamed or lowly foamed heat-fused layer, and non-foamed surface skin layers composed of a propylene-type polymer and laminated respectively to both surfaces of said laminated foamed sheet material, the ratio of the thickness Ts of each of said surface skin layer to the solid thickness Tf of each of the cured foamed sheets, Ts/Tf, being from 1 to 50, the thickness T1 of the heat-fused layer being 0.1 to 0.5 mm, and the thickness T1 being 1 to 25% of the thickness of each of the cured foamed sheets.
