Deep drawing is a form of metal forming, where rigid tools such as punch [1], die [2] and blank holder [3] is used. The blank is placed between the die and the holder and then deformed by the punch pushing the sheet into the die and the blank finally assumes the shape of the die. The metal plate is fixed between the die and the holder before processing begins, this prevents the formation of undesired deformations such as wrinkles.
Deep drawing changes metal sheets into curved parts or create curved parts with smaller diameter from already curved details. Often a series of deep draws are done to achieve the final shape.
