A big anniversary: On December 5, the 50th Barbara Colloquium took place at Aalen University. More than 170 participants accepted Prof. Dr.-Ing. Lothar H. Kallien's invitation to discuss current developments in the industry.
In his welcoming speech, Kallien (pictured, 5th from right) addressed the economic challenges facing foundries. In this context, he spoke about topics such as energy efficiency and resource conservation, which are particularly important for the industry. According to the professor, the exchange of knowledge is “particularly important” in these areas.
Presentations cover broad spectrum of the industry
Numerous specialist presentations from industry and research provided important impetus. Prof. Dr.-Ing. Dierk Hartmann from Kempten University of Applied Sciences spoke about measures to increase energy and resource efficiency in a medium-sized hand-moulding foundry. According to him, increasing efficiency in production is a major part of this, whereby the sustainable use of resources is “essential”. Hartmann also explained various strategies and technologies for reducing energy consumption in production and improving resource conservation.
Denis Babojelic (B. Eng.) from Lethiguel GmbH presented an innovative technology for optimizing melting processes through precise temperature control. He introduced isothermal melting using electric immersion heaters and showed how these can be used to ensure a constant melting temperature.
Uwe Gauermann (Dipl. Ing.) from Electronics GmbH presented new measuring technologies that can help to improve quality in the production of large components. These technologies enable more precise monitoring and control of production processes, resulting in higher product quality and lower reject rates.
Prof. Dr. Dr. Friedrich Klein concluded with a historical review of the 50-year tradition of the Barbara celebration at Aalen University and emphasized the importance of this event for the foundry industry. He highlighted the development and change of the celebration with a few anecdotes over the years.
Students present Master's theses
The program also included short presentations by students who explained their innovative master's theses. Matthias Middelmann presented new approaches for the use of sand cores in foundry technology, including innovative processes that can improve efficiency and quality when using sand cores in die casting. Annike Bossert gave an insight into innovative processes for implementing wood structures in die casting. Valentin Ziegler investigated the influence of alloying elements on mechanical properties and the CO2 footprint of aluminum alloys.
A traditional highlight of the Barbara Colloquium was the foundrymen's evening in the foundry laboratory at Aalen University. In a relaxed atmosphere, the participants had the opportunity to network and discuss the topics of the day.
