    摘要： A slush molding process in which the moldable thermoplastic composition powder dosed to the mold is prepared by blending ethylene carboxylic acid copolymers or ionomers with ethylene/glycidyl acrylate or methacrylate copolymer and cross-linking promoter at a temperature and for a time that does not cause significant cross-linking prior to dosing to mold, which is held for sufficient time and temperature to cause cross-linking in-situ, and optionally, other additives including release agents.

    摘要： A molding arrangement and method, such as slush or rotational molding, for forming a thermoplastic shell or skin product. The mold arrangement includes a hollow mold housing provided with a mold shell thereon, which together define an air chamber located within the mold housing. A plurality of air flow control devices, such as centrifugal fans, are mounted within the mold housing and direct heated air into the air chamber through discharge channels defined within the mold housing. The mold arrangement also includes an elongate air supply and heating arrangement which generates heated air within the mold housing and along substantially the entire longitudinal extent thereof to effect uniform heating of the mold shell.

    摘要： An apparatus for slush molding a thin shell having an outer layer and an inner layer. The apparatus includes two tubs alternately movable to a cast position for dispensing their respective material contents into a mold cavity. According to another embodiment of the invention, the apparatus includes a diverter valve configured to alternately open a passage from each of two tubs to the mold cavity to selectively dispense charge materials from the respective tubs into the mold cavity. In addition, a method is provided for forming a thin shell having an outer layer and an inner layer. A first polymer material is cast and allowed to melt on a heated mold surface to form an outer layer. A second polymer material is then cast and allowed to melt and form an inner layer on the inner surface of the outer layer. The shell is then removed from the mold.

    摘要： A rubber glove is produced by sequentially performing the step of immersing a glove mold in a coagulating synthetic rubber latex containing synthetic rubber in latex form, thermally expansible microcapsules, and a rubber coagulant to form a coagulant-containing synthetic rubber film on the surface of the glove mold; the step of immersing the glove mold in rubber-incorporating latex to form a gelled rubber layer; the step of heating a rubber laminate composed of the synthetic rubber film and the gelled rubber layer to vulcanize the rubber laminate; and the step of turning the vulcanized rubber laminate inside out, and removing it from the glove mold. This method produces a rubber glove, which is excellent in anti-blocking properties and grip under dry or wet conditions, by a simple procedure and for a low cost.
