As a result, the same types of produced parts decrease and therefore the use of tools with a lifetime of nearly 10,000 parts gets a higher attractiveness. For forming operations with a low production volume or even for the design or try out process, deep drawing tools made out of polymers can be used. To enhance the wear behaviour of the tools, it is possible to protect the polymer by a hard metal coating. One of the main advantages of the polymer material in such a tool is the possibility to change or influence the stiffness. By varying the stiffness, the material flow can be controlled. This is useful to influence the geometry deviation and the springback behaviour of deep drawn parts. The use of an elastic tool leads to a broad process wmdow for the forming operation. In the presented research results the possibility of the influence of stuffiness variation in polymer tool is investigated for two forming processes of DP 600 high strength steel. A comparison of the forming behaviour with polymer die and steel die is operated in these investigations. In the polymer die, the stiflhess could be varied by the use of metallic springs and electrical linear actuators. Thereby the stiffness was controlled temporally and locally.
