The theoretical principles of ironing thin-walled containers are discussed. Special attention is devoted to the development of a new, potentially less-expensive tin mill product (2.8/0.34, No. 25/03, differentially coated tinplate) to obtain the condition of differential friction in ironing. Experimental work demonstrated that 2.8/0.34 differentially coated tinplate performs satisfactorily in the drawing and ironing of beverage and food cans. Information is presented to show that 2.8/0.34 differentially coated tinplate is suitable for beer and less-corrosive soft drinks and for a wide variety of foods except for extremely aggressive products.
