Using conventional deep drawing method, it is difficult to make cups or containers taller than the diameter of the cup in only one stage drawing. This is because, in case of using a blank with large diameter, the drawing resistance of the blank material is too high to draw material into die hole by punch. From simple consideration, by using the developed blank, the flange portion of which is divided into four elements just like a petal, the drawing resistance of blank material can be reduced considerably, and so this problem can be overcome. In this investigation, a deep drawing process was attempted using a developed blank instead of a conventional circular or square blank. At first, by introducing two assumptions of the parallel moving and the constant arc length, the shape of developed blank was designed. After that, the effects of the shape of developed blank on the drawn cup were investigated. Finally, it was clarified that, when developed blanks with appropriate shape was employed, very tall cups could be obtained in one stage drawing.
