Werner Hähnel discusses tool costs and tool life are decisive for the performance of an extrusion line.

The pure tool costs are always put in relation to the service life achieved. Furthermore, the use of premium tool steels increases the product quality because the premium grade has a higher strength and toughness. The use of premium tool steel is also more economical because fewer tools have to be changed and thus there is a higher availability of the extrusion press. In addition, premium tool steels enable the production of particularly critical profile geometries.
