Salt Core Technology

Residue-free cavities in cast components

Our salt cores are mainly used in foundry technology for the realization of cavities in cast components. Compared to conventional sand cores, our natural product convinces with a residue-free removal by simple rinsing. Our raw material salt is characterized by unlimited availability, environmental friendliness and good water solubility.

Taking ceramic fundamentals into account, we produce our cores using a proven and economical technology, the uniaxial dry pressing process. Together with our customers, we develop forward-looking solutions far beyond foundry requirements. This constant further development of the systems allows our salt cores to be used in high pressuredie casting today.
