Rolling Process: Types, Working, Terminology and Application

Rolling is a major manufacturing process of sheets and other cross sections of large length like I beam, railroads etc. It is one of a metal forming process in which the metal work piece is compressed between a set of rolls where it reduces its cross section area and increases its length. This process gives high production rate, surface finish ...

Understanding metal roll forming and its tooling

Metal imperfections are common and can create problems during the roll forming process. They can even occur during the roll forming process. Using tension-leveled steel or aluminum coil helps. Tension leveling is the process of pulling metal beyond its yield point to permanently alter its shape and make it flat.
