1. A method for molding a composite object, the method comprising:

  • applying an adhesive to a first object of a first material;

    curing the adhesive;

    heating the first object;

    placing the first object in a mold so that a surface of a protrusion of the first object abuts an interior surface of the mold to prevent the surface of the protrusion from being covered by a second material to be injected into the mold in a molten state;

    injecting the second material in the molten state into the mold so that the second material surrounds the first object to form the composite object, the second material flowing into a slot in a perimeter of the protrusion of the first object so that when the second material solidifies, a rib of the second material extends into the slot in the perimeter to form a pressure seal between the first object and the second material;

    removing the composite object from the mold, wherein the;

    protrusion of the first object extends through the second material so that the surface of the protrusion is substantially flush with an exterior surface of the second material; and

    stabilizing the composite object until dimensions of the composite object stop changing.
