Description: The manufacturing process of aluminium cans consists of deep drawing cups from circular blanks cut from a EN AW-3104 (AlMg1Mn1) alloy sheet of maximum thickness 0.3 mm and then of a sequence of drawing operations (redraw, wall-ironing and can-bottom reverse drawing), all completed in one step. The sheet material must be of minimum anisotropy to avoid major earing during deep drawing which may cause clip-off during subsequent re-draw and wall ironing. This interactive animation schematically shows the various stages of the can forming process: initial draw, redraw and wall ironing.
