Ryka Molds Inc., Mississauga, Ont., is investigating blow molding applications for a new mold-cooling technology developed by RiTemp Technologies Pty Ltd., Edwardstown, South Australia. Ryka has acquired an exclusive development license from RiTemp for blow molding in North America. “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 license arrangement for injection molding has been reached with moldmaker StackTeck of Brampton, Ont. RiTemp’s evaporative cooling approach 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 is said reduce cycle time by 20% to 50%. Tel: (905) 670-1450 * www.rykamolds.com
