Ryka Molds Inc., Mississauga, Ont., is investigating blow molding applications for a new mold-cooling technology developed by RiTemp Technologies in Australia. Ryka acquired a development license from RiTemp and set up an application development center for blow molding. “Ryka and RiTemp believe this technology will significantly improve productivity for blow molders in the same way injection molders have seen significant gains previously unachievable,” said Ryka president Rick Hanke. A similar arrangement for injection molding applications has been reached with moldmaker StackTeck of Brampton, Ont. The RiTemp technique 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). A heat exchanger with chilled water condenses the steam back to water. The technique claims to reduce cycle time while also cutting energy and water consumption. (416) 625-1041 • www.rykamolds.com
