  • Two position double injection molding apparatus
    Patent number: 7210917
    Abstract: An apparatus and method for injection molding of molded products including a first cavity chamber for forming a seal liner, with the first cavity chamber having an outer edge, and a second cavity chamber for forming a shell, with the second cavity chamber having a center and being adjacent to the first cavity chamber. The injection molding apparatus and method also includes a first nozzle for a seal liner material positioned near the outer edge of, and in communication with, the first cavity chamber, and a second nozzle for a shell material positioned near the center of, and in communication with, the second cavity chamber. The injection molding apparatus and method further includes a mold core capable of being positioned in and moved between the first and second cavity chambers.

  • Method and apparatus for distributing melt in a multi-level stack mold
    Patent number: 7122145
    Abstract: An improved melt distribution system and method is provided for a multi-level stack mold having three or more moving platens. The injection machine communicates with a bifurcated sprue bar for providing pressurized melt through the first moving platen to a central distribution manifold in the second moving platen. From the central distribution manifold, the flow of pressurized melt is distributed to the first and third platens for transfer to a plurality of mold cavities.
