ritemp technologies

Using fundamental laws of physics, Ritemp technology reduces scrap by improving the thermal performance in Moulds. Ritemp increases the cooling system life and reduces mold maintenance. There are 6 distinct differences between the Ritemp process and other mould “cooling methods”

1. Physics of latent heat of evaporation

For every 1 gram of water evaporated, 540 cal/deg C of heat is absorbed using latent heat of vaporisation. Other cooling methods generally rely on turbulent flow of water, where water absorbs only 1 cal/gram/deg C.  Therefore, Ritemp enables a significantly more efficient cooling process to occur in the mould and inserts.

2. Ritemp uses chambers (Not channels)

Based on Ritemp design principles cooling chambers are machined to follow the geometry of the moulding surface, creating even steel thickness between the product and the cooling chamber. This increases the wetted surface area resulting in even shrinkage and good dimensional stability at fastest possible cycle time.

Machining chambers rather than gun-drilling channels can simplify machining. Any common machining method used in industry can be used such as high speed machining and spark erosion. With more complex geometries additive manufacturing techniques can be used.

3. Ritemp removes heat in two stages

Ritemp cooling removes heat in two stages: 1. Rapid & even heat removal around the heated surfaces through latent heat of vaporization. 2. The 2nd stage takes the heat out of the mould using the whole cycle. A reduction of 60-85% water use is common when compared against conventionally cooled moulds.

4. Ritemp reduces the external water circuits

A mould normally requiring 40-50 external circuits and around 400L/min can be reduced to 2 or 4 at 50L/min. Thus saving set-up time and pumping of water.

5. Ritemp cooled moulds do not condensate

Ritemp cooling does not pump cold chiller water directly on the core and cavity steel. The chamber environment is stable at set temperature.

6. Closed Loop System

The Ritemp controller controller regulates the flow of coolant from the chiller (or tower) based on the heat dissipation generated during the cycle. This means that external water only flows when required.
