Hot-runner supplier Mold-Masters Ltd., Georgetown, Ont., has obtained rights to exclusive global use of Ritemp evaporative cooling technology for hot-runner molds. The technology was developed by Ritemp Technologies of Austrialia, whose sole Americas agent is Ygrene Technologies, Inc., Burlington, Ont. Ritemp’s approach uses a sealed chamber in a mold insert behind the cavity. The
chamber is partially filled with water at a partial vacuum. This causes the water to boil as it removes heat from the melt and then recondenses as the heat is passed to conventional cooling channels alongside the sealed chamber. Cooling efficiency is said to be increased 300% because the latent heat of vaporization of water is much greater than the heat capacity of liquid water. Joint development with Mold-Masters over the last year demonstrated that the Ritemp technology provides faster cycles with drastically reduced water usage and completely uniform cooling, since the evaporative chamber can cover the molding surface evenly, unlike standard water channels. In many commercial applications, Ritemp technology used in mold inserts reportedly has achieved 30% shorter cycles and more uniform shrinkage while reducing coolant flow by an order of magnitude.

Ritemp technology is being demonstrated at NPE2012 this month in a four-cavity mold built by StackTeck, Brampton, Ont., in the booth of Sumitomo (SHI) Demag, Norcross, Ga. The mold will show, for the first time, both a Ritemp hot half and a Ritemp cold half. The mold will run 39% faster, using 55% less water flow, than the same mold with conventional cooling, according to StackTeck.
