We had never used the DT Cores before.  We would have built traditional hydraulic unscrewing molds but instead we chose the DT Core design based on its promise of reliability, clean process, and reduced cycle time.  Also with its shorter length design, this core fits within the parameters of our present molding machines.  The first shot came out perfect.  Not only did the DT Cores offer the space-saving benefit, which was huge for us, but the fact that we can cool the cores is a big factor because in the long run we can save money, especially with the heat and materials we are using for plastic.  The cycle time benefit is just phenomenal – I don’t know how else to express that.  And no scrap – our first shot comes out perfect, with no scrap.  Our mold techs are happy, too, because we are estimating reducing maintenance times by 90% based on what we’ve seen so far.
