摘要： A protector made of thermoplastic resin to which a foaming agent is added is adapted such that no foams are present in the thermoplastic resin forming a predetermined volume area including lock portions mounted on a protector body for integrating the protector body and a lid element but foams are present in the thermoplastic resin forming the area other than the predetermined volume area, whereby a molded part of thermoplastic resin is provided which accomplishes weight reduction and an insured strength at a strength-required area.

摘要： A method of making a foam injection molded article is disclosed wherein corrosion of the mold element is significantly reduced or substantially eliminated. The method comprises dispersing effective amounts of a primary chemical blowing agent of sodium borohydride and an activation system of sodium bicarbonate/citric acid mix into a polymer resin to form a mixture. The mixture is then heated whereby the activation system releases water and the sodium borohydride reacts with the water to produce hydrogen gas. The mixture is subsequently injected into a mold to obtain expansion of the polymer resin to form the foam article. The invention also comprehends a corresponding chemical blowing agent composition.

摘要： This apparatus is used to improve the heat distribution on the cavity surface in foam molding dies where a smooth finish on the resin filled foam molded plastic product manufactured by an injection molding process is desired. This invention improves the method for heating the mold cavity using a condensing vapor in a molding die by a channel and slit type orifice means in the mold around a portion of the periphery of the part to be molded. Another channel and slit type orifice means around the remaining periphery is included in the die for removing the condensing vapor or condensate from the mold cavity. During the heating process when condensing vapor is introduced into the mold the sprue opening to the extruder is sealed by a valve means to prevent condensate from collecting therein.

摘要： Plastic blown ware is made by expanding a molten plastic tubular blank into contact with the wall of a mold cavity. This invention evacuates air from the part of the cavity around the outside of the blank to increase the pressure differential across the tube wall during the blowing period and to help prevent the plastic from pulling away from the cavity wall during cooling and shrinkage. The invention makes blown ware by compounding the plastic with a blowing agent and by controlling the bubble size and wall thickness by changing the pressure on opposite sides of the blown article to whatever pressure will permit the gas bubbles and the plastic to expand to the desired size during cooling and setting of the plastic.
摘要翻译：塑料吹塑制品通过将熔融的塑料管状坯料膨胀成与模具腔的壁接触而制成。本发明将空气从坯料的外侧排出空腔，从而在吹塑期间增加跨越管壁的压差，并有助于防止塑料在冷却和收缩过程中从空腔壁上拉开。本发明通过将塑料与发泡剂混合并通过将吹塑制品的相对侧上的压力改变到允许气泡和塑料膨胀至所需尺寸的任何压力来控制气泡尺寸和壁厚来制造吹塑制品在塑料的冷却和固化过程中。

摘要： A floral base is made by hot wire cutting a foam of expanded polystyrene beads, thereby forming a smooth skin over the cells at the cut surface; differentially wire brushing the hot wire cut surface, lightly in some areas so that the wires only slice the surface skin and more deeply in adjacent areas so that the wires gouge out beads to form cavities and roughly parallel channels; then coating the surface with a latex paint. The resultant material surprisingly simulates the appearance of rough weathered lumber.

摘要： A filter assembly includes a monolithic thermoplastic structural element having parallel sealing surfaces, the element being either a filter frame or a filter support. The material of the element is denser at its surface than in its inner portions. When the element is a filter support, it has a system of filter grooves extending in its surfaces, which may be connected to a discharge outlet by way of a further groove which has a dimension increasing toward the discharge. When the element is a filter frame, it may be provided with a support body in the sludge space, having bases parallel with the sealing surfaces of the element. One or more inlet ports to the sludge space of the frame are provided, which flare outwardly toward the sludge space. The element may be provided with oval or circular recesses extending from edges between the parallel sealing surfaces, and the element may be provided with a projection on its edge, to which a holder may be affixed. If the element is a filter support, two edge corners may be bevelled and provided with projections to enable a filter sheet to be held thereto by way of clips on the projections.

摘要： An article, such as a door, is made from a colored water-extended thermoplastic polymeric material, and is provided with a decorated pattern by fusion of a surface layer to form a non-cellular layer, the depth of fusion being different in different parts so that the depth of color is correspondingly different. The variation in color intensity provides a decorative pattern, and fusion of the cellular material is effected by pressing with a die in the shape of the desired pattern.
