What Is Cold Forming Process?

Cold roll forming is a bending process wgere the bending occurs gradually in several forming steps from an underformed strip top a finished profile. The process is very interesting for the sheet metal industry due to the high speed in which the profile can be produced. High strength steel has, in recent years, become more common in cold roll forming.

How Does the Cold Roll Forming Process Take Place?

In cold roll forming a profile is formed in several forming steps from an undeformed strip to a finished profile. The forming process is geometrically complicated due to the fact that the forming does not only occur in the tools but also between each forming stand.

When creating the tools, the tool designer must decide how mony forming steps the profile demands. The number of steps is dependent on the shape of the cross-section, tolerance, thickness and the material properties. Therefore, the knowledge of how high strenth steel affects the number of forming steps is important.

Advantages of Cold Roll Forming

During this process, an extremely fast production process takes place using metal plastic molds. The reason why cold roll forming is preferred is that there is little material consumption and a strong product is obtained.
