Vom 17. bis 19. Januar 2012 dreht sich im Messezentrum Nürnberg alles um Druckguss. Rund 400 Aussteller und 7.000 erwartete Fachbesucher aus ganz Europa treffen sich auf der EUROGUSS, Fachmesse für Druckguss-Technik, -Prozesse und -Produkte. Neu ist die Sonderschau "Forschung, die Wissen schaf(f)t", auf der sich Universitäten, Institute und Hochschulen mit ihren Studiengängen, Forschungsschwerpunkten und Dienstleistungen vorstellen. Unter den Teilnehmern ist auch die Gießerei Technologie Aalen (GTA), die Prof. Dr.-Ing. Lothar Kallien leitet. Wir besuchten Kallien im Vorfeld der Messe in seinem Gießerei-Institut und sprachen mit ihm über aktuelle Forschungsprojekte, innovative Verfahrenstechniken sowie den Austausch zwischen Forschung und Industrie.
