Two central topics of modern automotive constructions refer to automotive lightweight
constructions and safety; this is best indicated by the most various developments in the context of
body constructions. The consistent evaluation of cars by means of crash tests has led to the fact that
new manufacturing variants combined with the use of high and ultra high strength materials
represent a fundamental part of the body in white. One possibility to form such materials is given by
the hot forming process. An innovative approach, namely to improve this procedure in economic
and technological terms, is represented by the new tool system for tempered forming processes
carried out at the Institute Tools & Forming (T&F). The integration of most complex cooling duct
geometries by casting integral tube networks into the tool represents an innovative possibility to
improve the cooling performance combined with the reduction of the cycle times.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
