Freiberg, the historic silver city with its deeply rooted industrial heritage, recently hosted a major industry gathering: After previous editions in Duisburg, Aachen, Munich, and Clausthal, the 5th Moulding Materials Forum was held in Saxony – an event that impressively bridges ancient foundry traditions with cutting-edge research and innovation.
The forum was officially opened in the grand library of the Technische Universität Bergakademie Freiberg by BDG-Service GmbH. Professor Michal Szucki, head of the Foundry Institute and host of the event, emphasized Freiberg’s unique position: “Freiberg continues to evolve without forgetting its history – just like the casting process, which dates back over 5,000 years and is still being refined today through new materials and technologies.”
The spotlight was on modern developments in moulding material technology: the use of inorganic binders, the integration of additive manufacturing such as 3D printing, and strategies to minimize environmental impact. Even in 2025, casting remains a highly adaptable and relevant process for the sustainable production of complex metal components.
The TU Bergakademie Freiberg, on whose campus the forum took place, further reinforced its reputation as a center of excellence for science and research. Founded in 1765, the university now comprises six faculties and 42 institutes – including the renowned Foundry Institute. With its fully equipped pilot plant, advanced analytical tools, and state-of-the-art testing facilities, it offers ideal conditions for research, education, and industry collaboration.
Current research projects highlight the institute’s innovative strength:
-
Development of wear-resistant steel alloys for construction machinery components
-
Filtration concepts for the reuse of aluminum scrap
-
Optimization of simulation models for core shooting processes
-
CO₂-free melting of non-ferrous metals
-
Regeneration of various moulding material systems
Through close collaboration with industry partners, the institute contributes significantly to the competitiveness of the foundry sector – while also advancing environmental protection.
The forum brought together a diverse mix of industry representatives, researchers, and professional associations. The organizers were pleased with the lively exchange of ideas and the shared goal of strengthening the link between science and practice. As recognized as early as the 18th century, industrial progress relies heavily on scientific support – a principle that remains more relevant than ever.
True to the spirit of the opening speeches, the forum evolved into a vibrant platform for open dialogue, new partnerships, and forward-thinking solutions. Contributions from industry users, suppliers, and research institutions explored key topics such as sustainability, resource efficiency, energy optimization – and ever-larger component dimensions. Thanks to technological advances, even sand-based megacastings are becoming a realistic prospect.
