METHOD OF DRAWING/IRONING OF RESIN-COATED METAL SHEET AND DRAWN AND IRONED RESIN-COATED CAN FORMED BY THE SAME

摘要

A method of the drawing/ironing of a resin-coated metal sheet which comprises drawing a resin-coated metal sheet comprising a metal sheet and an organic resin with which at least one side of the sheet is coated and then ironing it with a punch and adjacent dies to thereby mold a can comprising a bottom, a side-wall part, and a flange-forming part. By the method, barrel breakage accompanying a reduction in the thickness of the can side wall can be effectively prevented. Furthermore, a drawn and ironed can having a thickness reduced to a predetermined value can be efficiently molded.
