Disclosed herein is, amongst other things, a molding apparatus that includes a core ring ( 140, 340, 440, 540, 640, 740) that is configured to seat, in use, around a core insert ( 120, 320, 420, 620) in a mold stack ( 1 16, 216, 316, 416, 516, 616, 716). The core ring ( 140, 340, 440, 540, 640, 740) is configured to be received, at least in part, within a pocket ( 152) that is defined within a split insert ( 150) of the mold stack ( 1 16, 216, 316, 416, 516, 616, 716). The core ring ( 140, 340, 440, 540, 640, 740) is also configured to define at least a portion of a molding cavity ( 1 19) having a core ring-to-split insert parting line ( 180) that is within the pocket ( 152) of the split insert ( 150).
