Abstract: Methods for molding a surround over a liner to form a composite shell are provided. The liner is placed in a mold and molten surround material is injected into the mold so as to surround the liner. A surface of a protrusion of the liner abuts the mold so that the surface is exposed and is substantially flush with an exterior surface of the surround after the composite shell is removed from the mold. Molten surround material flows into a slot in a perimeter of the protrusion so that when the surround material solidifies, a rib of surround material extends into the slot to form a pressure seal between the liner and the surround. An adhesive is applied to the liner before placing the liner in the mold for reducing relative movement between the liner and surround as the surround material solidifies and the liner and surround cool.
