The defect of aluminum cans called “short can” is related to the loss of continuity of the material when the aluminum is stretched between tools, which successively reduce the diameter of the can and are called “flattening”. The can wall breakage phenomenon is called “short can” and is related to the lower height compared to a full-value product. This occurs when the continuity of the material is broken during the reduction of the sidewall thickness, generating a defect in the height and shape of the can.
