    Abstract: A process for producing a fiber-reinforced molded article and the resulting article such as a cantilevered battery tray. In the process, thermoplastic material in its solid state having a melt flow index above 25 g/10 minutes is fed into a suitable processing machine simultaneous with the addition of reinforcing fibers having a length of at least 0.375 inch or greater and sized with a material such as polyurethane, polyurea, and isocyanate derivatives thereof. The introduced materials are subjected to orientational agitation such that the reinforcing fibers are filamentized in an essentially homogeneous dispersion throughout the solid polymeric material. Once filamentization and dispersion are achieved, the resulting admixture is subjected to knead melting operations for an interval sufficient to achieve melting of the polymeric material introduced into a suitable plasticizing apparatus where the introduced material can be subjected to suitable knead melting operations.

    Abstract: A method and system for producing hollow rib structures for trim components and panels using gas assisted injection molding. Movable insert members are provided in the mold cavity, particularly at the ends of the structural rib members. After the plastic material is injected into the mold cavity, the plastic is packed in the mold, and the insert members are locked in position. Selectively activatable locking mechanisms are used to lock up the insert members. Thereafter, gas or another fluid is introduced into the rib members in order to provide hollow channels therein. Movement of the insert members provides a recess or groove for placement of the displaced resin from the rib members. The displaced resin material completes the formation of the molded plastic article.

    Abstract: A design of microchannels and a method for economic production of such microchannels. The new microchannel design comprises a thin thermoplastic film and a relatively thick substrate to form microchannels in-between. The microchannels are displaced on the film side. The method for fabricating such microchannels is a hybrid process combining compression, and blowing or vacuum forming to form microchannels between the film and the substrate. During the process, the film is placed on the top of the substrate. A mold or die with to-be-replicated microchannels clamps the film against the substrate. Either blow molding or vacuum forming is then carried out to deform the film and replicate the microchannels. Rapid heatable and coolable molds are preferred to soften the film and form bonds between the film and the substrate while short cycle time is maintained.

  • Publication number: 20030075837
    Abstract: The invention provides a method and apparatus for injection moulding a plastics article having thin and thick wall sections (14; 15). A quantity of molten plastics material (19) is introduced sufficient to fill the mould cavity, followed by a further quantity of molten plastics material sufficient to pack at least the portion or portions of the mould cavity in which the thin wall section or sections (14) are formed. Pressurized fluid is introduced through the or each fluid injection member to penetrate the plastics material whereby a fluid-filled void (20) is formed within the plastics material adjacent to the inner end of the fluid injecting member, and fluid pressure is maintained within the or each void so that the void expands in response to the shrinkage of the immediately surrounding plastics material, during cooling, until the plastics material is self-supporting.

  • Publication number: 20030007891
    Abstract: Designs and methods of manufacture are disclosed for a fluid detecting device. The fluid detecting device includes a colorant or dye used as the fluid indicator. When the dye comes into contact with the fluid, the reaction between the dye and the fluid is used to evaluate or detect the presence of fluid in the device. The reaction of the dye with the fluid may be detected using visualization, nephelometry, spectrophotometry, infrared detection, nuclear magnetic resonance spectroscopy or other techniques.

  • Patent number: 6503586
    Abstract: The present invention relates to a polyester polymer composition containing inorganic black particles in the range of about 5 to about 150 parts per million based on the polymer. The size of the inorganic black particles is greater than about 0.5 microns. Such polyester polymers having inorganic black particles incorporated therein absorb infrared radiation better than polymers containing no inorganic black particles and thus in the production of plastic bottles less energy is required to blow-mold the bottles.

  • Publication number: 20020163106
    Abstract: An injection mold apparatus having two halves, a core portion and a cavity portion. One or more gas injection devices, such as porous metal devices, are located in either of the two portions of the mold. Once a charge of hot melted plastic is injected into the mold cavity, gas is injected through gas injection devices forcing the hot plastic against the opposite mold half and into any recesses and grooves. Gas seals are formed by the plastic to prevent gas in the mold cavity from reaching the exterior surface of the molded part during shrinkage of the plastic. The centers of mass of the plastic at rib intersections are optimally positioned to eliminate sink marks on the external finished surfaces of the molded parts.

  • Publication number: 20020070470
    Abstract: The invention relates to a method for injection molding a plastic molded part in an injection mold, comprising a) injecting a specified amount of plastic melt into the injection mold; b) introducing a compressed fluid between a part of the wall of the injection mold and the injected plastic melt; c) allowing the plastic melt to cool until the plastic molded part is self-supporting; and d) removing the plastic molded part from the mold. The invention specifies that, during or after step a) and during or before step b), the cavity of the injection mold is sealed against the environment, preferably by activating at least one seal.

  • Patent number: 6403014
    Abstract: A mold apparatus and method is used to form a solid injection molded plastic part having no internal voids, a Class A finish, a sink-free exterior appearance surface, and unevenly distributed structural detail extending from the opposite surface, the detail including free-standing reinforcement ribs, attachment bosses, and the like. In sequence, a seal groove in the mold cavity is reduced to a pressure below atmospheric (i.e., negative), a charge of hot thermoplastic is introduced into the mold cavity and seal groove whereby to form a gas seal ring, and pressurized gas is injected into the mold cavity. The pressurized gas forces the hot plastic from one mold half against the other mold half, and the gas seal formed by the plastic prevents gas on one side of the thermoplastic from reaching the appearance surface of the part.
