Cold rolling is a metalworking process that involves the deformation of metals at room temperature. This technique enhances the mechanical properties of metal sheets, including strength, hardness, and surface finish. Unlike hot rolling, which is conducted at high temperatures, cold rolling minimizes the risk of oxidation and enables better dimensional control. The cold rolling forming machine combines this process with a shaping mechanism that prepares metal for various applications.
