  • Patent number: 6808661
    Abstract: A system is proposed for encapsulating in plastics material leadframe items comprising an IC wired to a leadframe. Dust of the plastics material is removed from the encapsulation system, and in particular from those items where dust principally accumulates, such as the surfaces of the molds. To reduce the level of dust which enters the molding region, the path along which the leadframe items are conveyed to the molding region is closed at times when the leadframe items are not being transported there. Additionally, the leadframe items are conveyed to the molding region under a cover including a vacuum source, so that the dust is continually sucked away from them.

  • Patent number: 6793870
    Abstract: The invention relates to a method for linking a first plastic component (6) with a second plastic component (9). According to the inventive method, the first component (6) is introduced into an injection mold with at least one connecting section (12) at which the link with the second component (9) is to be established. The second component (9) is formed by injection-molding plastic material onto the connecting section. A surface of the connecting section (12) is at least partially covered by the plastic material of the second component (9). At least one of the components may consist of a plastic material that requires only a relatively narrow temperature range to be moldable in the molten state. At least one binder body is formed at the surface intended to be covered by the injection-molded plastic material which binder is firmly linked with the surface. Said binder melts when contacted with the heat energy of the injection-molded plastic material and fuses with the injection-molded plastic.

  • Patent number: 6787091
    Abstract: A method of molding a layer of a thermoset or thermoplastic material around a golf ball component within a mold, in which the component is positioned within a mold cavity defined by opposing mold portions of the mold, to leave a cavity space between the component and the mold portions. A reaction mixture comprising at least two reactants is injected under a hydraulic pressure into the cavity space. The pressurized reaction mixture pushes the mold portions apart from each other to a partially open position with an opening therebetween. The reaction mixture is allowed to react partially within the cavity space, and then the mold portions are compressed toward each other to the closed position. The reaction mixture further reacts to form the layer of the thermoset or thermoplastic material immediately about the component.

  • Patent number: 6787094
    Abstract: Sleeve molding apparatus and methods for making multi-layer injection molded plastic articles in successive mold cavities. In a first molding step, an inner sleeve is molded on a core in a first mold cavity, which may comprise a full body length sleeve or only a partial sleeve, such as an upper neck finish portion. The sleeve and core are withdrawn from the first mold cavity while the sleeve is still warm, and transferred without substantial delay to a second mold cavity for injection molding an outer layer which bonds to the inner sleeve. By transferring the sleeve at an elevated temperature into the second mold cavity, an improved bond is formed between the inner sleeve and outer layer which resists separation during a later reheat stretch blow molding step, and/or in use of the resulting article. In a preferred embodiment, a pasteurizable beer container is provided having a finish-only sleeve of a PEN polymer.

  • Patent number: 6775848
    Abstract: Pore-free rubber articles are prepared by dip-molding in a dipping medium that includes a vulcanizing agent, then by immersing the dip former in a heated liquid bath that is chemically inert. A particularly effective liquid bath is molten inorganic salt. In addition, the tensile properties of an article of vulcanized rubber can be improved to an unusually effective degree by immersing the already vulcanized article in a solution of a vulcanizing agent to cause the rubber of the article to absorb or imbibe the vulcanizing agent from the solution, and then immersing the rubber and the imbibed vulcanizing agent in a heated liquid bath to increase the degree of vulcanization.
