Cold forming is a new process and new technology of sheet metal forming that saves material and energy. Cold roll forming equipment Cold roll forming (Cold Roll Forming) is the continuous horizontal bending of coils, strips and other metal plates through sequential multi-pass forming rolls to make profiles with specific sections.
The cold-formed forming process can not only produce section steel products, but also shorten the product development cycle, improve production efficiency, and improve the market competitiveness of enterprises.
In recent years, cold-formed steel products as important structural parts have been widely used in many fields such as construction, automobile manufacturing, shipbuilding, electronics industry and machinery manufacturing. Its products range from ordinary guide rails, doors and windows and other structural parts to some special profiles manufactured for special purposes.
The section performance of cold-formed steel per unit weight is better than that of hot-rolled steel products, and it has high surface finish and dimensional accuracy.
Therefore, cold-formed steel can achieve the dual effect of saving steel and energy by replacing hot-rolled steel. Great attention has been paid to the development of bent steel. It is the constant desire of users for the varieties, specifications and quality of cold-formed steel products of cold-formed equipment that has promoted the rapid development of cold-formed technology.
