• The purpose of this paper is to show dissimilarities between the Marform process and the hydroforming. Firstly, the forming pressure distribution over the rubber die surface is clarified from the measurement. Secondly, it is emphasized that the deformed profile at the forming radius portion determined theoretically agrees fairly well with the experiment considering the above pressure distribution and the frictional force between a sheet metal and a rubber die. Finally, it should be noted that the frictional force at the side wall portion does not always play so important a role as in the hydroform method in preventing the concentration of the forming force at the punch profile portion. The product of the drawing ratio 2.76, however, can safely be obtained by regulating the forming pressure so as to make good use of the frictional force.
