Deep drawing process is a vital sheet metal forming process used in domestic and automotive industry. In this process blank material is changed into the desired complicated shape by punch. In this research paper, an elasto-plastic part for Mild Steel IS 2062 material as received has been developed to scrutinize the behaviour of the flange wrinkling and deep drawing parameters under different Blank-Holder Pressure (BHP = 2.5 to 9.5 MPa). This study is discussing about the technological possibility for acceptable products. The present process successfully produces shape with drawing ratio of 2.0. Simulation results are critically studied and salient conclusions have been drawn. An experimental setup is built accordingly with a half cone angle of 40°. The outputs of finite element simulation are used to investigate the effect of blank-holder pressure on product integrity and mechanical properties. The experimental results were compared with FE results. An experimental setup is built accordingly with a half cone angle of 40°.
