Each bodymaker contains a tool called a punch, which forms the shape of the can by forcing the cup through a series of progressively smaller circular ironing rings. This action literally draws the metal up the sides of the punch, ironing it into a can body. As the cup is forced through the rings, its diameter is reduced, its walls are thinned and its height is increased. At the end of the punch stroke, the bottom is formed into a dome shape that strengthens the bottom of the can. During this process, referred to as wall ironing, the can must be lubricated to reduce frictional heat. This is a high-speed process producing 1,500 to 2,700 can bodies per minute. The lubricant is constantly recirculated through a filter and reused.
