What is a cold roll forming machine?
Release time: 2018-04-13

Cold roll forming is a new process and technology of metal sheet material saving, energy saving and high efficiency. By using this process, not only high-quality steel products can be produced, but also the product development cycle can be shortened and production efficiency can be improved, thereby improving the market competitiveness of enterprises.
In the past half century, cold roll forming has developed into an effective sheet metal forming technology. Strips 35 to 45 rolled in North America are processed into products by cold forming, which is more than steel used in the automotive industry. In recent years, cold-formed steel products have been widely used as important structural parts in many fields such as construction, automobile manufacturing, shipbuilding, electronics industry, and machinery manufacturing. Its products range from ordinary rails, doors and windows and other structural parts to some special profiles made for special purposes, with a wide range of types. The cross-section performance per unit weight of cold-formed steel is better than that of hot-rolled steel products, and has a high surface finish and dimensional accuracy. Therefore, replacing cold-rolled steel with hot-rolled steel can achieve the dual effect of saving both steel and energy. The development of curved steel has been given great attention. It is users' constant desire for the variety, specifications, and quality of cold-formed steel products that promote the rapid development of cold-formed forming technology. The computer simulation and finite element analysis of cold roll forming are the hotspots of theoretical research. There are many papers and research results published at home and abroad.
