Progressive die stamping is a multi-stage sheet metal forming process, where the final shape is given in two or more sequential operations. Those operations can be blanking, forming, drawing, piercing, tapping, staking, etc. Each station along the path performs a specific operation simultaneously each time the die descends until the part is complete.
To carry out this process a strip of sheet metal is pushed by the feeding system through all of the stations of a progressive stamping die. The final station is typically one in which the finished component is cut from the strip of metal that transported it through the press.
On the following picture is possible see how the metal sheet is transformed with the desired shape.
