        The side wall thickness variation of the product to the process of ironing and the die pad was studied using a progressive die of the multi-stage drawing product in the process of ironing and the die pad. Experimental results because ironing is possible to increase the side wall thickness of the product is applied to the intermediate drawing process rather than applied in the initial process. The roundness and concentricity were easy control. A die pad is applied to a stand pad to the sixth step from the first step. The seventh step and the eighth step are applied integrated pad. The integrated pad of the seventh step and the eighth step appeared to be advantageous to control the roundness and concentricity.
