Abstract—Short run production are the current scenario for batch production is of growing importance. When considering metal forming processes in this scenario, die and punch costs play an important role making the processes costlier. Polymer composite material, Renshape 5166 dies made by rapid tooling techniques prove to be good solution in this scenario. Fatigue life estimation of the dies help in planning for the production. FE simulations are carried out to predict the fatigue life of these dies during deep drawing process. The results of the simulation indicate that these dies can be used or softer material like aluminum for 1000 cycles, but when stronger materials like Cu or SS are used, the life is limited to around 100 cycles.
