The draw-iron can was developed to compete with aluminum alloys for pressurized beverages containers, which have become the highest growth market for cans, due to their popularity for dispensing drinks.
In the draw and iron technique, the can is made in two steps.
A disc is blanked from sheet stock, and drawn into a cup.
The can is lengthened or deepened by ironing the sides in a stretching operation that reduces wall thickness to about one third of its original gauge.
The drawn and ironed can is then washed clean of lubricant lithographed, interior spray-coated, necked-in and flanged.
A two-piece cup-like can ready to receive contents and a double seam end is the resulting product.
