  • Gas-assisted injection molding with a carpet layer
    Patent number: 5162092
    Abstract: A process for injection molding a thermoplastic backing (12) or other synthetic resin to a carpet layer (14) by suspending the carpet layer (14) between two mold halves (46,48), injecting a thermoplastic resin into the mold, and injecting an inert fluid such as nitrogen into the mold at a relatively low pressure to assist in distribution of the thermoplastic resin throughout all points of the mold. The invention also relates to a synthetic resin backed carpet, which resin backed carpet may constitute a vehicle dashboard (10). The vehicle dashboard (10) can include an internal runner or rib (16) which has a hollow portion (52) formed substantially along its length, the hollow portion (52) being formed by injection of the inert fluid during the injection molding process.
