It was investigated that plenty of the processes of shape wire drawing process designed by trial and error relying on experience of industrial experts. In consequence of this process, it is inevitable that the increase of product cost, unnecessary time consuming, and effort. In case of manufacturing the final product with asymmetric section geometry and high aspect ratio, the concentration of strain at a side caused the severe distortion of the wire and low-cycle fatigue resistance is formed. The objective of this study is to design process of multi-pass shape wire drawing from initial round material with consideration of the cross section geometry of the final product. First, the multi-pass shape wire drawing process was designed by equivalent potential line in electric field analysis. The reduction ratio of area was calculated by relationship to the number of pass in multi pass shape wire drawing process determined by capacity of drawing machine and drawing force. In order to take account of concentration of strain of cross section of wire, the process for multi shape wire drawing from initial round material to an intermediate die was redesigned using electric field analysis again. In this study, the either drawing process design was estimated by finite element simulation in which the strain distribution and standard deviation plastic strain of the cross section of drawn wire.
