    摘要: An improved machine for the production of foamed plastic molded parts, including soft foam plastics, i.e. for processing particles without foaming capacity, and including the processing of greatly frothed plastic foam particles, i.e. particles with but little foaming capacity, is obtained in that a pressure equalization system is provided which creates virtually equal pressure conditions while the mold cavity is being filled, i.e. the same overpressure in the material supply line as in the mold cavity. This makes it possible to introduce the foam particles, already compressed in the material supply system, into the mold cavity in a continuous flow by means of an injector, with excess foam particles being blown back into a tank provided in the material supply system by the injector after the mold cavity is filled. Due to this operating principle, the machine can be designed so that it can be set up for the processing of different materials such as soft foam particles, rigid foam particles and greatly expanded rigid foam particles.

    摘要: Mold, particularly for rigid polyurethane foam articles having finished textured surfaces on all sides thereof comprising a female mold having a recess into which the unreacted and unblown resin system is deposited and a cover for closing the mold together with a release sheet structure disposed therebetween exhibiting sufficient gas porosity to enable complete venting of air displaced by the rising foam in the production of a finished surface thereat and method of molding therewith.

    摘要: A plastic vent insert for communicating to atmosphere a molding chamber in which foam plastic parts are molded. The insert, which is preferably made from either polyethylene or polypropylene is mounted in one of the mold members. The vent passage extends through the insert from the molding chamber to atmosphere. Air within the molding chamber and gases generated therein during foaming escape through the passage so that voids are eliminated in the foam part. Any foam which intrudes into the passage may be readily removed.

    摘要: Provided is a method for producing a foamed synthetic resin molded body. In this method, in the case where a hole-like portion is a through hole, when foam molding is performed, the occurrence of molding defects such as voids at the periphery of the hole-like portion can be sufficiently prevented or suppressed without forming a burr portion that closes the hole-like portion. Also in this method, in the case where the hole-like portion is a non-through hole, the occurrence of molding defects such as voids at a bottom portion of the hole-like portion can be sufficiently prevented or suppressed.

    摘要: An article including a substrate having a first surface, an opposing second surface and a peripheral edge defined between the first surface and the second surface. A shaped foam body made of a polymeric material is attached to the substrate. In the space between the peripheral edge of the substrate and a peripheral edge of the shaped foam body, there is a margin that is substantially free of any polymeric material of the shaped foam body, and a border area that includes an exposed extension of the polymeric material of the shaped foam body having a substantially predetermined shape and size. A tool and process for making the above is described as well.
