Leader Pins, Vents and Bushings

   Leader Pins and Bushings align both halves of the mold at the parting line. Leader Pin Vents, which allow trapped air to escape from the mold, are designed into all 15-inch-and-wider series molds. When desired, they can be specified on smaller molds.

  Provides positive alignment between adjacent plates when mold has one or multiple parting line openings. This provides close alignment for interlock cavities and coresin stripper plate type molds.

Locating Rings

  The Locating Ring aligns the mold base to the statinary platen side of the press and positions the sprue bushing corretly.
