  • Rotational molding with removable fixture
    Patent number: 5911938
    Abstract: A molded unit is made using a rotational molding process. In making the molded unit, a tool assembly houses the mold material. A fixture assembly is also contained within the tool assembly. The fixture assembly holds an insert member in place. The insert member becomes an integral part of the molded unit during the rotomolding process. Preferably, the insert member is spaced from the inner walls of the tool assembly in order to permit mold material to flow and solidify in this space. The fixture assembly is removable from the interior of the molded unit through one or more access openings that are formed in the molded unit.
