Innovation for Foundry Technology
For the Swedish foundry Ljunghäll AB, our team at Emil Müller GmbH has recently started producing salt cores for a cast component from the automotive sector. After salt cores have already been used for gravity die casting and low-pressure die casting, they are now being used for the first time in a high pressure die casting process.
Previously, both cooperation partners had gone through an intensive development phase and successfully implemented various new technologies - such as the production of the salt cores at the Wilhermsdorf site in a customised powder press from Frey & Co GmbH. For Ljunghäll AB, in addition to the process development of the die-casting method, the washing out of the salt cores after the casting process and the subsequent treatment of the process water were added as further process steps.
