    摘要： The present process includes a mold for producing a thermoplastic resin molded article, comprising paired sliding female and male mold members, which mutually slide at the time of mold closing. A product-forming portion and a non-product-forming portion are provided in the cavity of the mold, the mold further including a resin-supplying opening. A gate portion located at a boundary between the product-forming portion and non-product-forming portion interconnects the two portions. At closing of the mold, the width of the gate at the product-forming side is less than the thickness of the formed product, and stepwise or continuously widens toward the non-product-forming side. Using this mold, a thermoplastic resin molded article, with or without a laminated skin material, can be molded in good efficiency and low cost, further having a non-product-forming portion, which can be readily trimmed from the product-forming portion.

    摘要： The present invention provides a process for producing a multilayer molded article having a skin material laminated with at least a part of the surface of a substrate formed of a thermoplastic resin. The process has steps of supplying a skin material to between a pair of mold halves and supplying a molten thermoplastic resin to between the skin material and the molding surface of one of the mold halves. The process uses, as the skin material, a skin material which has at least a foamed urethane layer and a nonfoamed backing layer wherein the product of the density, &rgr; (g/cm3), of the foamed urethane layer and the weight, W (g/m2), of the backing layer is not less than 2. This process prevents crush of the foamed urethane layer and can produce a multilayer molded article with good appearance.

    摘要： Disclosed is a system in which carbon dioxide is supplied to a pressure chamber of a molten resin preparing apparatus which has established a certain temperature environment to diffuse the carbon dioxide in a material synthetic resin in a molten state. After turning the material synthetic resin into a gas-dissolving-resin in the pressure chamber, the gas-dissolving-resin is supplied to a mold space of a molding apparatus for compression molding. The pressure inside the mold space is quickly lowered by raising an upper mold of the molding apparatus quickly, whereby a foamed article is produced from the gas-dissolving-resin in the mold space.
