The importance of cold roll forming
Cold roll forming is a new process and technology of sheet metal forming that is material-saving, energy-saving and highly efficient. Utilizing this process, not only can we produce high quality steel section products, but also can shorten the cycle of product development, improve production efficiency, so as to improve the market competitiveness of enterprises.
In just the past half century, cold roll forming has developed into the most effective sheet metal forming technology. In North America rolled out of the strip 35% to 45% is processed by the cold-formed molding products, more than the automotive industry steel.
In recent years, cold-formed steel products as an important structural components in construction, automobile manufacturing, shipbuilding, electronics industry and machinery manufacturing and many other fields have been widely used. Its products from ordinary rails, doors and windows and other structural components to some for special purposes and manufacture of specialized profiles, the type is extremely wide. Cold-formed steel section performance per unit weight is better than hot-rolled steel products, and has a high surface finish and dimensional accuracy, so the cold-formed steel instead of hot-rolled steel can be achieved not only to save steel and energy saving double effect, so people attach great importance to the development of cold-formed steel. It is the user of cold-formed steel product varieties, specifications, quality and other aspects of the constant desire to promote the rapid development of cold-formed molding technology.
