Cold drawing is the process of reducing the cross-section of rolled steel by passing it through an open mold. The process is carried out at ambient temperature without extra heating. After the cold drawing process, surface sensitivity increases and elongation occurs in the length direction. After this plastic forming process, changes in mechanical values are achieved. The open mold, called sealer, with the help of the applied push and pull forces, eliminates surface defects such as scale and porosity, and provides a shiny and relatively smooth surface by scraping from the surface as well as cross-sectional contraction. In addition, the post-processing dimensional tolerances of the steels passed through these molds with precise tolerances are refined. This process can also improve mechanical properties. Hardness, Yield and Tensile Strengths can be increased by cold drawing process in varying amounts according to the forming ratio. Although cross-sections such as round, square, wedge, hexagonal are generally seen in cold drawing process, special design cross-section shapes can also be produced. Although it is generally seen that the cross-sectional shape of the shaft entering production and the shaft exiting production are the same, it is possible to change the cross-sectional shape in the cold drawing process with different mold designs.
