  • Load bearing panel member and method for forming a load bearing panel member
    Patent number: 8221673
    Abstract: The present invention provides a method for producing an injection molded panel member having a first portion, a second portion, and an appearance surface portion. The method includes placing the appearance surface portion of the panel member into a mold cavity. The mold cavity preferably includes a first chamber adapted to form the first portion of the panel member, and a second chamber adapted to form the second portion of the panel member. After the appearance surface portion of the panel member is inserted into the mold, molten plastic material and pressurized gas are injected into the first chamber of the mold cavity. After the molten plastic material is injected into the first chamber of the mold, molten plastic material is injected into the second chamber of the mold cavity. The molten plastic is then cooled until it solidifies. After the molten plastic is sufficiently cooled, the pressurized gas is vented and the panel member is removed from the mold.
