Additiv hergestellte Strangpresswerkzeuge: Produktivitätssteigerung durch den Einsatz von konturnaher Innenkühlung

Research output: Journal contributionsJournal articlesResearch


The influence of a local inner die cooling on the heat balance in hot extrusion was investigated. For the manufacturing of the dies with conformal cooling channels close to the forming zone two additive manufacturing methods were used. This new tooling technologies were applied in order to decrease the profile’s exit temperature and to avoid thermally induced surface defects with the aim to shift the extrusion limits to higher speed and therefore to raise the productivity.
