Emil Müller GmbH was founded in 1921 for the production of sheet metal packaging and established itself in the following years with stamped and bent parts as a permanently reliable automotive supplier. For more than 40 years now, Emil Müller GmbH in Wilhermsdorf has successfully produced approx. 40 million salt cores per year for piston casting as well as complex salt core geometries for customer-specific applications.
With our specialized and profound know-how, we have opened up new markets worldwide and founded subsidiaries in Poland, Brazil, Mexico and India. As a result, the Emil Müller Group, a wholly owned subsidiary of CeramTec, now comprises more than 220 employees.
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 die casting today.
