ABSTRACT:
A method and apparatus of embedding separated elements in a molded member wherein at least one side of the separated elements is covered by the molded member. The separated elements are interconnected by links to form a unitary member, which is disposed in a mold cavity formed by first and second mold plates. A support pin positioned on a first side of the unitary member supports the unitary member while a punch pin is extended toward a second side of the unitary member and through the link interconnecting the elements so as to sever the link. At least one of the punch pins or the support pins is retracted away from at least one side of the separated elements before injecting a molten material into the cavity so as to form the molded member.
