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 high pressuredie casting today.
The use of our salt core technology for the realisation of cavities is very diverse and offers decisive technical added value compared to conventional production in the automotive, aerospace, industrial and leisure sectors.
With the help of our salt core technology, complex cavities with an excellent surface quality can be realised in the casting for various applications.
Our environmentally friendly, sintered salt cores are used on an industrial scale for the realisation of piston cooling channels and can also be used in other casting processes due to their very high strength.
With a large number of patents for, among other things, various binder systems and salt preparation, Emil Müller GmbH is a convincing technology leader in the field of salt core technology.
Our bonded salt cores have been used serially in gravity die casting for decades.
