Moldmaker StackTeck of Brampton, Ont., is exploring applications for a new mold-cooling technology patented by RiTemp Technologies Pty. Ltd., Edwardstown (Adelaide), South Australia. StackTeck is seeking partners for production of small to medium-sized prototype tools to evaluate the cooling technology, which was fi rst unveiled here at the NPE 2006 show in Chicago. The RiTemp approach is an evaporative cooling approach that uses large cooling chambers machined out of the core and cavity sides of the mold instead of conventional gun-drilled cooling channels. The sealed chambers contain water under low vacuum so that it boils at low temperatures (50 F). At the top of each mold half, a heat exchanger with chilled water condenses the steam back to water. This approach greatly simplifi es the entire mold-cooling circuit and is said to speed molding cycles by 20% to 50% while eliminating hot spots and mold sweating.
