Analysis of the manufacturing process of beverage cans using aluminum alloy

The parameters involved in the beverage cans manufacturing process have been analyzed by many authors. These parameters are used to determine the quality of the raw material before it is used to manufacture the cans. It is shown that the strain-hardening exponent together with the forming limit curve can predict whether the sheet metal will have a good drawability throughout its length. It is also shown how much others parameters such as angle of the ironing die, friction coefficient and clearance between punch and ironing die influence the ironing force and consequently the manufacturing process.
