INTRODUCTION :
The aluminum beverage can is made with two pieces — the can body and the can end (or lid). The manufacturing process starts with coils of aluminum. Can plants use mass quantities of aluminum coil every day to make can bodies or ends. Each coil typically weighs about 25,000 pounds and, when rolled out flat, can be anywhere from 20,000 feet to 30,000 feet long and five to six feet wide.
1: The aluminum coils arrive at the can plant and are loaded one at a time onto an "uncoiler" —a machine that unrolls the strip of aluminum at the beginning of the can making line and feeds it to the line, where it is first lubricated. Lubrication helps the aluminum flow smoothly during the can shaping processes.
