      A - Edge Orient
       In the edge orientation,
      the parting line in the mold is straight with no bends or contours.  This
      simplifies the molding process and mold assembly. 
       Metal
    flow in the edge orientation will be smooth and direct into the
      two sections of the arm.   The
      cores for the center bores will sit horizontally securely positioned in the bottom/drag section of the mold.
