Mounting the hollow cylinder on the draw punch may include tightly fitting the hollow cylinder around the lower punch portion. The method may further include forming the double layer cup-shaped part by drawing a blank material through a draw die by placing the blank material over an upper opening of the draw die, and pressing the draw punch over the blank material.
