Designed and engineered in Australia, Ritemp technologies is bringing a revolutionary cooling process to the world wide moulding industry.
With technology partners in America, Ritemp provides uniform mould temperatures regardless of the shape of the mould.

The revolutionary cooling process for the moulding industry.

Ritemp™ is a revolutionary new process. Its primary objective is to overcome one of the key problems with the moulding process, namely variations in the surface temperature of the mould.
Ritemp provides highly uniform mould temperatures regardless of part geometry. Hot spots are eliminated. To demonstrate the problem we show here a simple mould set up with conventional cooling using drilled channels.

Conventional Cooling Process:
• Cooling provided by drilled hole techniques is inherently uneven.
• The efficiency of heat removal is rarely satisfactory.
• The need for turbulent coolant flow creates the need for high coolant velocity. This need for velocity conflicts with the need for surface area with which to extract heat.
• Differential cooling rates cause cause distortion of the product and variations in surface finish.
• Multiple cooling circuits are frequently needed to enable compensation for differences in heat input / output rates
• Corrosion in complex cooling circuits results in costly maintenance
• Cooling is often compromised due to the positions of ejector pins, screws and hot runner systems.

Ritemp Solution
Ritemp™ eliminates all of the problems mentioned previously. The RiTemp™ process is described bellow by using the same mould example.
Shelling is combined with Cooling by Evaporation. All air is evacuated from the cooling chambers. This allows water to boil at very low temperatures. Heat is extracted from the mould by converting it to Latent Heat of Vaporisation.

This is an extremely efficient process.
• The resultant vapor rises to the top of the mould where it is condensed by specially designed heat exchangers.
• The water will always boil where it is hottest and condense where it is coolest.
• This process ensures that the temperature throughout the mould is evened out automatically so that a high degree of uniformity is maintained.
• The need for running multiple cooling circuits at different temperatures is eliminated.
• Since oxygen is not allowed into the cooling process chambers, corrosion is not possible.
