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.

Are you interested in our products & solutions? We look forward to hearing from you.

Our sintered salt cores in many dimensions and shapes

With the help of our salt core technology, complex cavities with an excellent surface quality can be realised in the casting for various applications.

Large-scale production for the reproduction of oil-bearing cooling channels

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.

Customised solutions for customer-specific applications

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.

More than 40 years of know-how in salt core technology

Our bonded salt cores have been used serially in gravity die casting for decades.
