To produce a 2-piece drawn and ironed (D&I) steel can, a coil is fed into the cupping press and the initial cup is drawn. The cup is conveyed into a body maker where a die punches it through a series of rings at a significant force. This results in the cup walls being ironed or stretched to a predetermined height, followed by trimming which produces the final can size. Fast speeds and seamless side-and-bottom container integrity are just two plusses of D&I produced cans.

A pioneer in steel D&I food cans, Silgan has amassed significant experience in state-of- the-art manufacturing. In fact, the company has more food D&I manufacturing lines than any other U.S. food can producer.
