Roll forming is a process of continuous bending operation of a long strip of metal. The metal strip is passed through sets of rolls; each roll performs an incremental part of the bend. This process is continued till the required cross section profile is obtained. Roll form is the most common and ideal method for producing metal parts in long lengths or in huge quantities. The process of roll forming is a simple manufacturing process in which a device called dispenser holds a large metal strip. A machine with a stock feeder, which is attached to a cutoff attachment, is fed with this unrolled metal strip. After this process, the metal strip is passed through the forming rolls. Desired shapes are achieved from these metal strips, because of the mating die–set rolls in this machinery, which achieve different shapes in various stages, by means of various shaped rolls. These roll configurations can be flower shaped, progressive upper/ lower rolls, cluster roll configuration or side rolls. They are used according to the shape that needs to be achieved. Thus roll formed parts can have variety of curves, angles and shapes. All kinds of ferrous and nonferrous metals can be formed through the process of roll forming. Nowadays companies provide cost effective methods for roll forming requirements of customers. A wide variety of roll formed parts are offered, and the task is performed with complete expertise in the field. State of the art machinery is used to produce results which meet customer demands. Innovative techniques are used to reduce cost and increase quality. These companies have expert staffs that are up to date with their knowledge in roll forming. Advanced roll forming machineries are used which produce highest quality, economically priced parts. There are numerous processes that can be performed while roll forming is being done. Multi secondary work can be eliminated in roll forming. Roll forming is considered beneficial than metal forming processes because there are fewer component parts required in roll forming, there is less material wastage, there is closer tolerance in roll forming, there are variety of materials used and manufacturing cost is lower, and they offer greater strength than metal forming. Different types of metals can be roll formed, thus allowing end user to have variety of options to design products according to customer requirement.
This method of roll forming produces parts which cater to the following industries – transportation, sporting goods, store fixtures, mining, material handling, furniture industry, food services industry, farming, construction, automotive and appliance industry.
