Roll Forming

The Process Roll Forming
Roll forming, sometimes spelled rollforming metal sheet metal forming process is a form of progress through a series of bending operations. The process is conducted in line roll forming sheet metal stock is fed through a series of roll stations. Each station has roller, roller means death, where both sides of the plate. Shape and size of the die roll may be unique to the station or like a death roll, many of which may be used in different positions. Wheels death may be the top and bottom sheet with sides, corners and other sheets are forced through the roller die stations, each coil is plastically deforms and bowed station roll each step in the completion of the bending of the plate. forms part of the requirements. Wheels are die lubricant to reduce friction between the die and sheet, which reduces engine wear. In addition, lubricants can allow a higher production rate, which depends on the thickness of roll stations, and the radius of each curve. Roll forming line also includes the performance of other fabricated metal plate before or after roll forming, such as punching or cutting.


The roll forming process can be used to form a sheet into a wide variety of cross-section profiles. An open profile is most common, but a closed tube-like shape can be created as well. Because the final form is achieved through a series of bends, the part does not require a uniform or symmetric cross-section along its length. Roll forming is used to create very long sheet metal parts with typical widths of 1-20 inches and thicknesses of 0.004-0.125 inches. However wider and thicker sheets can be formed, some up to 5 ft. wide and 0.25 inches thick. The roll forming process is capable of producing parts with tolerances as tight as ±0.005 inches. Typical roll formed parts include panels, tracks, shelving, etc. These parts are commonly used in industrial and commercial buildings for roofing, lighting, storage units, and HVAC applications.
