  • High volume production of low permeation plastic fuel tanks using parallel offset twinsheet pressure forming
    Patent number: 6969485
    Abstract: Processes are disclosed for producing plastic containers from thermoplastic sheets where the thermoplastic sheets are processed in parallel to form a low permeation plastic container. A plurality of thermoplastic sheets are progressively heated to a first temperature in a pre-conditioning stage. A group of the thermoplastic sheets are selected from the plurality of thermoplastic sheets and rapidly heated to a second temperature in a final heat stage. The group of thermoplastic sheets are then processed in a forming stage to form the low permeation plastic container.

  • Low hydrocarbon emission fuel tank with internal components
    Publication number: 20020020705
    Abstract: A low permeation fuel tank formed with a first half and a second half includes a hydrocarbon barrier and a fuel system module. The hydrocarbon barrier reduces the emission of hydrocarbons from the fuel tank. Minimization of discontinuities in the hydrocarbon barrier is achieved by positioning the fuel system module within the fuel tank. The fuel system module includes a preformed sheet to provide flexible and rigid support to the fuel tank. In addition, the fuel system module may include fuel system components, structural enhancements of the fuel tank and/or functional features of the fuel tank to minimize production of holes or other discontinuities in the hydrocarbon barrier.
