Abstract
A method is provided for molding an integral joint including a stationary member and an enclosure rotatable about the stationary member. The method utilizes a joint formation assembly defining an inner cavity, a first passageway connected to the inner cavity, an outer cavity surrounding the inner cavity, and a second passageway connected to the outer cavity. The method includes the steps of: introducing moldable material into the inner cavity from the first passageway to form the stationary member; introducing moldable material into the outer cavity from the second passageway to form the enclosure; and divorcing the inner cavity from the outer cavity for separately and independently forming the enclosure around the stationary member to allow rotatable movement of the enclosure about the stationary member.
