n A small orifice between runner and cavity in an injection or transfer mold. Such a gate freezes (or cures) quickly when the cavity has filled and flow stops, preventing packing of the region near the gate in the cavity. When the piece is ejected, this gate breaks cleanly, simplifying separation of the runner from the molded item. It may be so small (see  Pinpoint Gate) that its tiny stub need not be removed from the piece.
