Monitoring of Cooling Circuits in the Mold Casting Process with Pressure Sensors

The cooling of molds during the casting process, for example of engine blocks, is a key criterion for obtaining a finely solidified casting product through a constant cooling speed of the melt. For the water cooling of the individual cast iron mold sectors, several separated cooling circuits are needed. Pressure sensors installed front-flush in the narrowest of spaces measure both pressure and temperature in each return line simultaneously – with high accuracy via IO-Link. The high thermal conductivity of cast iron and the solidification of the objects can therefore be controlled precisely.
