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.

摘要： A mold device includes a mold member having a mold cavity for receiving a melted foamable material to form an object, and a pressure applying device for applying a pressure to the melted foamable material, and to limit a foaming of the melted foamable material, and for preventing orifices from being formed in an outer peripheral portion of the object, and for forming a smooth and shiny or sparkling outer appearance to the object. A mold piece is movably received in the mold cavity, and an actuator may force the mold piece to force against the melted foamable material. A pumping device may pump the hydraulic fluid into and out of the actuator.

摘要： Making foamed bodies by introducing a biodegradable polymer mixture into a mould (10) in which it is heated to form a foam and to fill the mould. The mould is defined between two opposed parts (12, 14) that mate together, and each mould part is of electrically conducting material, and the moulding surfaces are coated with an electrically insulating material (16). Radio-frequency signals are applied (25) between the mould parts (12, 14) so that the polymer mixture is heated by dielectric heating, so a foam tray is formed in less than 15 s. This provides a more rapid cycle time than using heated moulds. The radio frequency signals may be 27.12 MHz, or 40.68 MHz. The polymer may be starch-based.
摘要翻译：通过将可生物降解的聚合物混合物引入到其中被加热以形成泡沫并填充模具的模具（10）中来制造发泡体。两个相对的部分（12,14）之间的模具被限定在一起，并且每个模具部分是导电材料，并且模制表面涂覆有电绝缘材料（16）。在模具部件（12,14）之间施加射频信号（25），使得通过介电加热来加热聚合物混合物，因此在少于15秒内形成泡沫托盘。这比使用加热模具提供了更快的循环时间。射频信号可以是27.12MHz或40.68MHz。聚合物可以是淀粉基的。
