Seen this on line, used to eject the part, some molds have a hole where a blow gun is used, the valve stems will provide a positive seal. It is always a pain pulling a part out of a one piece mold. The valve stems are located on the areas that will cut out so no worry about making a mark on the finished part. Itis a first for me. I actually considered mading the mold two piece but didn't have a suitable parting board.
