Cold bending forming is a new technique and technology of sheet metal forming, energy saving and high efficiency.
Using this process, not only can produce high-quality steel products, but also shorten the cycle of product development, improve production efficiency, so as to improve the market competitiveness of enterprises. In the last half century, cold bending has developed into the most effective form of sheet metal forming technology.
Rolled steel 35%~45% in North America is made of cold-formed products, more than steel used in the automotive industry. In recent years, cold-formed steel products have been widely used in many fields, such as construction, automobile manufacturing, shipbuilding, electronic industry and machinery manufacturing, as important structural parts. Its products from ordinary rails, doors and windows and other structural components to some special use and manufacturing of special profiles, the type is extremely wide. The section performance of cold-formed steel unit weight is better than that of hot-rolled steel, and it has high surface finish and dimensional accuracy, so cold-formed steel can save both steel and energy by replacing hot-rolled steel, so people attach great importance to the development of cold-formed steel.
It is the users of cold-formed steel products, the variety, specifications, quality and other aspects of the constant desire to promote the rapid development of cold-formed technology.
