Ninety five percent of all beer and soft drink cans in the United States are made of aluminum. Bodymakers are a part of the process. Aluminum arrives at the facility on massive rolls and loaded onto a machine called an Uncoiler. It is then fed into a Cupping Press which makes a cup, or sometimes called puck, probably because it resembles a hockey puck.
The cup is then transferred via conveyor into a Redraw Press (more commonly known as a Bodymaker). The Bodymaker forms the shape and approximate height of the can. The final height is provided via a Trimmer. Cans are then printed on with the end user's brand and packaging information and then go into a curing oven. The last part of the process involves the use of a Necker Flanger, which narrows the opening to form a neck and flange.
