Abstract: Disclosed herein is, amongst other things, a mold stack that includes a core insert, a core ring, and a split insert that are configured to cooperate, in use, to define a molding cavity. The core insert defines a ring seat on a medial portion thereof upon which the core ring may be seated, in use, in cooperation with a mounting interface thereon. The split insert defines a pocket that extends coaxially through a second projecting portion thereof within which to receive a projecting portion of the core ring. The core ring and the split insert being further configured to define a core ring-to-split insert parting line that is within the pocket of the split insert. The core ring further defines a first split insert seat for receiving the second projecting portion of the split insert.
