METHOD AND SYSTEM OF MOLDING INTEGRAL JOINT

摘要

A method is provided for molding an integral joint including a stationary member and an enclosure rotatable about the stationary member. The method u tilizes a joint formation assembly defining an inner cavity, a first passage way connected to the inner cavity, an outer cavity surrounding the inner cav ity, and a second passageway connected to the outer cavity. The method inclu des the steps of: introducing moldable material into the inner cavity from t he first passageway to form the stationary member; introducing moldable mate rial into the outer cavity from the second passageway to form the enclosure; and divorcing the inner cavity from the outer cavity for separately and ind ependently forming the enclosure around the stationary member to allow rotat able movement of the enclosure about the stationary member.
