    Stretch forming of sheet metal. This is a method for drawing flat blanks or semi-finished blanks into open hollow parts using molds. It is widely used in the manufacture of high-precision parts and thin-walled parts. During the stretching process, the material will undergo axial and circumferential plastic changes, thereby changing the shape and size of the workpiece.
