To this day, GTS has developed into one of the leading manufacturers of industrial ceramics in Germany. The focus of our research and development work is, among other things, on special ceramics and attrition technology. Thus, ceramic grinding balls of top quality were already produced 35 years ago under the pioneering eyes of Horst Müller. Today, the expansion and further development of GTS are already being managed in a family business in the second generation. Both generations jointly contribute knowledge, competence and a high passion for ceramics.

Acquisitions of market companions have further consolidated GTS' established position as market leader for investment casting, jewellery casting, laboratory and medical technology. Our corporate mission statement continues to be characterised by quality and continuous further development. The focus of our work is on the consulting and direct exchange with our customers. We are happy to accompany projects that underline our research and development competence. In addition, we offer a wide range of standardised product groups at an attractive price in the well-known high GTS quality.

More than 50 universities and research institutes in Europe cooperate with GTS. For example, we have significantly influenced the development of artificial bone replacement, new ceramic qualities for platinum casting or reaction chambers for biogas energy generation. It is therefore important to us to be an active member of various organisations and research projects for innovations and new developments.

Andreas MüllerManaging Director GTS KERAMIK

Company Background

In 1985, Horst Müller founded the company FMCP on behalf of the Belgian stainless steel foundry Magotteaux S.A. with the original production plant for melting crucibles and an associated development laboratory in Düsseldorf. The focus of research was on the fields of special ceramics and wear technology. Thus, top quality ceramic grinding balls had already been created almost 35 years ago.

The parent company, Magotteaux S.A., benefited from these technical developments and established the grinding ball factory Megaceram S.A. in Belgium. As technical director, the pioneer Horst Müller was tasked with building the factory.

Several years later the production facility in Dusseldorf was to be privatised. Again, it was Horst Müller who made an important decision. He took over the Belgian branch and in 1991 founded GTS (Gieß-Technische-Sonderkeramik GmbH & KG). Over the next ten years, his path always led him back to the parent company. As a consultant, he put his meanwhile invaluable knowledge at the disposal of the Magotteaux group. In the meantime, he promoted the expansion and continued technical development of GTS.

Over time the success of GTS products led the company to expand. This positive development ensured that GTS became a well-established company in investment casting, jewellery casting, laboratory, and medical technology, and in some sectors even became the market leader. Due to the permanent growth of GTS, Andreas Müller was promoted to a management position in 2004. He set new and decisive impulses, allowing GTS to undergo another burst in development.

In 2005, GTS acquired the ceramic foundry Megaceram S.A. and shifted production from Belgium to Düsseldorf. The result was a further strengthening of GTS in the international market, resulting in increased involvement in research and development projects. Meanwhile, more than 50 universities and research centres benefit from this collaboration. Fields such as gel casting, isopressing, platinum melting, and the development of artificial bones, container crucibles for solar technology, and reaction chambers for biogas energy production were significantly influenced by GTS in jointly supported programmes.

Research and Development

As early as 1985, GTS was conducting research in special ceramics and wear technology. Thus almost 35 years ago, top quality ceramic grinding balls were already being created. GTS considers research and development in particular as the basis of innovation and the top quality of their products, because their maxim is:


The future opportunities for GTS consist, among much else, in their involvement with long-term complex research topics, up to the basic preliminary research. The knowledge gained from this provides the basis for the development of new products, and at the same time optimises existing products. This results, among other features, in high reusability numbers – not only our customers are delighted. The economical use of resources in terms of sustainability is guaranteed.

A network of over 50 universities and other research institutions collaborates with GTS. More than ever, this collaboration presents a win-win situation for both parties. The collaborative work is funded by support programmes by the EU, the Federal Republic of Germany, and Saxony.

Fields such as gel casting, isopressing, platinum melting, and the development of artificial bones, container crucibles for solar technology, reaction chambers for biogas and energy production are some examples.

To prevent becoming lost in uneconomic basic research, GTS is always in contact with their customers, always with the market in mind. Of particular interest here are jewellery foundries and smelting plant manufacturers.

Quality assurance

The company uses systems to identify potential errors through effective structural and process organisation, to analyse their causes and to prevent the occurrence of errors through suitable preventive measures. In order to achieve these goals, all employees are involved in the process of introducing and permanently securing the system. In order to ensure the effectiveness of these and other measures, the education, training and motivation of employees play a decisive role.

The raw materials used at GTS are exclusively purchased from certified suppliers under strict, controlled acceptance conditions.

In order to guarantee consistent quality in the long term, the stockpiling of critical raw materials is of great importance. GTS stores in particular the so-called "rare earths" in larger quantities. The undesirable capital tie-up resulting from this has paid off in the past through constantly rising raw material prices.

The intensive contact with our customers results in new impulses for quality improvements or trend-setting new developments. Mature, reproducible and traceable manufacturing processes guarantee a consistent product according to the highest quality standards through constant documentation.
