GEORGETOWN, ONTARIO (Feb. 29, 12:30 p.m. ET) — Mold-Masters Ltd. has formalized an agreement with Ritemp Technologies Pty. of Australia for exclusive use of Ritemp evaporative cooling technology in hot runner applications.
Mold-Masters is a hot runner supplier based in Georgetown, Ontario. The agreement is through Ritemp’s agent for the Americas, YGRENE Technologies Inc.
“Ritemp patented technologies intrigued us because it had the potential to provide faster cycle times, with less energy, drastically reduced water usage and complete uniform cooling,” said Bruce Catoen, vice president of business and product development at Mold Masters. “Joint developmental efforts over the last year have proven to us that these benefits are viable and we now are prepared to offer Ritemp hot runners commercially.”
The Ritemp process extracts heat from the mold by converting it to vapor, which rises to the top of the mold were it gets condensed by simple heat exchangers. The technology uses a fraction of the normal water needed and boosts cooling efficiency, said Ritemp, based in Edwardstown, Austrialia. It reduces cycle times.
At NPE 2012, the Sumitomo (SHI) Demag (Booth 2103) will run a four-cavity StackTeck mold with both a Ritemp hot-half and cold-half, running a spout at 7.2 seconds, a 39 percent improvement over a conventionally cooled mold.
