Abstract:
A method for fabricating a double layer cup-shaped part may include shaping a first material into a hollow cylinder, mounting the hollow cylinder on a draw punch, where the draw punch may include an upper punch portion with a first diameter and a lower punch portion with a second smaller diameter. 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. The first material may form an inner layer of the double layer cup-shaped part and the blank material may form an outer cup-shaped layer of the double layer cup-shaped part.
