Aluminum alloys have good anti-corrosion properties and strength to weight ratio. In this paper, a statistical method based on finite element simulation was used to obtain the highest percentage of mold filling and the minimum percentage of thinning in the forming area. First, the finite element model is prepared and the accuracy is compared with the results of the experimental part. Effective factors including, temperature, pressure, pressure rate, axial feed and punch speed were evaluated by the response surface method in order to extract the model and find the maximum effect. Design Expert software was used to model the response surface methodology and Abacus finite element software was used to simulate it. According to the obtained results, the optimal points obtained for both characteristics are: temperature 552°C, pressure 6.5 bar, bar rate 0.02 bar/s, axial feed 7 mm and feed rate 0.05 mm /s with filling percentage 91.2 and a thinning percentage of 10.37 were obtained. The proposed model for predicting the values of variables had very close results with the experimental findings.
