For mass production of stamped parts which do require complicated in-press operations, it is always advisable to use a progressive press. But it is difficult to choose progressive die if stamped pats need deep drawing and especially they are unsymmetrical. Because unsymmetrical deep drawing parts are very sensitive to the effect of weight during moving next stages, they are hard to be located exactly on die face. Automotive seat side cushion panel is about 80mm high, unsymmetrical and its low edge needs hemming, so it is hard to produce using progressive die. In this paper to adopt progressive stamping for seat side cushion panel, 5 cases of strip bridges are considered to be strong enough to move next stage die exactly by CAE analysis.
