Water unit for continuous core cooling 

The continuous core tempering offers many advantages in comparison to timed cooling. Continously dissipating the heat during the whole die casting process the leads to lower pressure on the cores and more homogenous temperature levels over the whole mould.  Better product quality and longer durability are the result.

Grundfos multistage pump

Water unit for continuous core cooling

The use of a multistage pump allows up to 10 cores with a cooling cross section of only 8mm² of to be connected
