  • Method and apparatus for encapsulating a ring-shaped member
    Patent number: 6248279
    Abstract: A method and apparatus for encapsulating a ring-shaped member, such as a wound coil of wire, a wound metal ribbon, or a metal composite material. The ring-shaped member is mounted upon a mandrel. The mandrel and the mounted ring-shaped member are positioned in a first mold. A thermoplastic material is injection molded peripherally about a first inner void between the mandrel and the ring-shaped member and a first outer void between the first mold and the ring-shaped member. The mandrel is moved with respect to the ring-shaped member. The mandrel and the re-mounted ring-shaped member are positioned in a second mold. The thermoplastic material is injection molded into a second inner void between the mandrel and the ring-shaped member and within a second outer void between the second mold and the ring-shaped member. The second fill of the thermoplastic material joins with the first fill to fully encapsulate the ring-shaped member.
