Hemming is a technology used in the automotive industry to join inner and outer closure
panels together (hoods, doors, tailgates, etc.). It is the process of bending/folding the flange of the outer
panel over the inner one by plastic deformation. Hemming of closure parts in the automotive industry
is a complex engineering process that has a lot of parameters to reach the required well-looking vehicle
trims. The process to obtain this result is related to closure parts designers, closure metal parts manufacturers,
and hemming capital equipment manufacturers. The responsibility of the final design of the part
and equipment cannot be decided unless a common feasibility study has been done. The study aims to
categorize a preferred matrix of a feasibility study and give technical important details of each task to
decrease the investment required for equipment, decrease trial and error, have a high-quality product,
optimize cycle time, and acquire a fast-commissioning period. This feasibility study of the matrix of
actions is relying on the result of each step and the difficulties faced in it. When an error or problem is
noticed a root cause is done after which the analysis should be reviewed from the beginning of the loop,
rechecking and optimizing each aspect.
