Drawing is a process involving the deformation of an input material, which may be in the form of a wire rod, rod or wire, through a die hole. The cross-sectional area of this hole is smaller than the cross-sectional area of the material being drawn through it. The result is a reduction in the diameter and an elongation of the workpiece. There may also be a change in the cross-sectional shape. During this process, the material is strengthened, resulting in an increase in its strength properties, but at the expense of a reduction in its plastic properties.
