  • Universal nozzle tip for injection molding
    Patent number: 6604933
    Abstract: An injection molding nozzle tip has a particular arrangement of geometries that allow a sharp &Dgr;t point to be effected at a transition section between a heat sink area (adjacent to an external mold) and a heated reservoir that contains molten resin. The high temperature differential at the &Dgr;t point is effective to remove stringing and drooling for a wide range of materials and nozzle sizes.
