Experiments are described, which use gas generator materials as a driving force in a deep drawing process. Two different tools for low and high pressure ranges were constructed. During the work a new gas generator material was developed, which shows a low slag formation and reduced combustion temperature. Decomposition kinetics and interior ballistic behavior were characterized. Materials tested were steel, stainless steel and aluminum with different thicknesses. The results show that gas generators are a suitable tool for deep drawing applications. The performance of the gas generator process is directly comparable to the hydroforming process, but the time for the drawing cycle is much faster with the new method.
