I asked Kevin about the mold and he said it does need the Twinjector. He is desiging new mold that does not use the blending block but will still need the Twinjector. The sprue on some molds just adds cost to the finished product if it cant be used again. But the if the sprue is long I cut them in half and remelt. He also said he is thinking about offering it in a 16 cavity mold too. It is real hard for me to justify that mold too. Frank
