Another metalworking process, drawing stretches metal with the use of tensile forces. Classified as a cold procedure, drawing is mostly done at room temperature; however, in case of large hollow sections, rods, or wires, it can also be performed at higher temperatures to reduce the applied force. Under this process, at the metal is drawn, it stretches into the desired shape and thickness. The process of drawing can be classified into two basic types. These are: sheet metal drawing and wire, bar, and tube drawing. Sheet Metal drawing involves plastic deformation over a curved axis, while wire, bar, and tube drawing involves pulling the starting stock through a die, thereby reducing its diameter and increasing its length.
Drawing depends on force applied locally near the area of compression, and the lack of transmission through the turning action of the mill is how drawing and rolling differ. The tensile strength of the material limits the amount of possible drawing force.
