  • De-gating mold for injection molding of elastic materials
    Patent number: 6887419
    Abstract: A multi-material runner gate system allows effective de-gating of elastomeric materials that would otherwise stretch and/or flex reducing de-gating forces at the gate upon separation of the molds.
    Type: Grant
    Filed: May 31, 2002
    Date of Patent: May 3, 2005
    Assignee: MGS Mfg. Group, Inc.

  • Self-contained frameless rotating mold support
    Patent number: 6709251
    Abstract: A support for rotating molds used in multi-shot injection molding provides for platen mounting of a support track that may extend beneath the molds to support the rotating mold portion. The extensible track provides a telescoping configuration that allows a long support span independent of the mold width improving mold stability and increasing potential mold separation for easy access to the mold portions.

  • Multi-shot, injection molded valve
    Patent number: 6371444
    Abstract: A multi-shot, injection molded valve has at least two independent elements which are rotatably and non-detachably connected together. The valve includes a stationary housing and a pitcock rotatably mounted therein. The stationary housing is molded in a first shot with at least one inlet projecting from one side of the housing and at least one outlet projecting from another side of the housing. The housing has a substantially cylindrical upper portion defining a first bearing surface, and a substantially cylindrical lower portion defining a second bearing surface, the upper and lower portions being divided by a substantially cylindrical rib. The pitcock is molded in a second shot with an external grip portion, an upper cylindrical segment beneath the grip portion and a lower cylindrical segment separated from the upper cylindrical segment by a substantially cylindrical undercut which is engageable with the rib on the housing.
