Abstract:
A method of drawing and ironing a resin film laminated metal sheet for forming a can body having a bottom portion, a can wall portion and a flange-forming portion by drawing the resin film laminated metal sheet obtained by laminating at least one surface of a metal sheet with an organic resin film, followed by ironing by using a punch and a plurality of dies neighboring each other. The can wall is effectively prevented from being broken by a decrease in the thickness of the can wall, and drawn and ironed cans are efficiently formed having a thickness which is decreased as designed.
