A roll forming machine (or metal forming machine) fabricates specific configurations out of long strips of metal, most commonly coiled steel. In most applications, the required cross-section profile of the piece is specifically designed for the machine to bend the metal as necessary. Other than roll forming, these machines perform a number of metalworking duties, including material cutting and roll punching.

Roll forming machines, for the most part, work in a continuous cycle. The material is fed into the machine where it continuously makes its way through the stages of each operation, ending with the completion of a final product.

A roll forming machine accomplishes the fabrication process by sending sheet metal—most commonly coiled steel—through a series of fixed rollers, which continuously and incrementally bend the metal into the required form. By progressively bending the metal bit by bit at strategically spaced rollers, manufacturers can customize cross-sectional shapes with exacting precision and uniformity. A typical speed for roll forming machines is anywhere from 30 to 100 feet of metal per minute, ensuring an incredible ongoing output of material.

Typically at room temperature, metal coils or sheets feed into rollers that guide the material to the first of the bending stations. Once there, a roller will precisely bend the metal and then drive it forward through the machine to the next station. Each station will continue to shape the component by bending it a little more, with capabilities for unique and complex part designs. The more contoured the design, the more roller stations the part will pass through.

After the metal makes its way through the rollers, the workpiece enters the cut off press, which cuts the metal to its specified length. Despite the nearly limitless length options, roll forming machines require only one set of tools for generating cuts. This machinery can also offer other in-line services such as welding or punching.

Ultimately, the finished component emerges onto a roller conveyor for a worker to retrieve. This is one of the few stages that may involve manual processing.  Added technology can run the machinery, precisely placing the metal for optimal cutting and checking for imperfections while reducing labor costs and material waste.

The formed end product will require minimal finishing work, if any, before packaging or storage. This is due to roll forming’s capabilities for producing finely detailed components with continuous finishes and few seams.

Roll forming is a flexible and cost-effective process for shaping metal into custom cross-section profiles. Often called “cold roll forming,” because the metal is shaped in its hardened state, roll forming is used across a wide range of industries to produce parts and components for everything from metal forming in automobiles to appliances to airplanes and houses.

For products that can be roll formed, the process offers a host of benefits and advantages over alternative approaches.

Efficiency

Most roll forming is done with long strips of metal in coils, so the process is high-speed, with low labor demands, allowing higher volume production for most products with higher efficiency than with press braking or stamping. Additional processes, such as punching or notching, can be incorporated into a roll-forming production line, further reducing labor demands, and outputting completed products ready for distribution. Press braking requires separate processes for punching, notching, or perforating, adding time, labor, and expense.

Savings

Roll forming is a no-heat system — reducing energy costs — that gradually bends the metal, in stages, into its final shape by passing it through a series of custom-designed rollers. Roll forming doesn’t create the tool wear that stamping does, the process eliminates the need for machining, such as deburring, often required with press braking. Identical parts cut from long strips mean no wasted scrap, and roll-formed parts can be of almost any length, while press braking limits length to the size of the machine. Roll-formed metal parts produced in quantity are almost always more cost-effective than plastic or extruded versions.

Flexibility

Even complex cross-section profiles that are a challenge or are impossible with stamping can be easily created with roll forming, including round, closed, and C-shaped profiles. Almost any metal, ferrous or nonferrous, can be roll-formed, while extrusion is limited to only aluminum or brass. Roll forming also allows the shaping of metals already finished with paint, plating, or coating, while extrusion works only with unfinished, unplated stock, and press braking of finished metals requires additional handling and processes, costing time and money.

Precision, Quality And Consistency

Roll forming can be designed to meet very tight tolerances. Products are more uniform and consistent across runs than with press braking, facilitating ease of use in applications such as assembly line manufacturing, where components must fit right every time. Roll forming can produce much higher quality products and components than extrusion.
