How Does a Roll Forming Machine Work?

Unlike other metal working processes, roll forming is a continuous process that shapes sheet metal into a desired shape.aluminum roll forming machine This is a highly efficient way of producing large quantities of metal components. The process produces uniform and clean contours, and results in few seams. The process does not require heating of the metal. During the forming process, the roll forming machine uses an array of rollers that work together to form a metal strip.

Each profile in the roll forming process requires a custom-crafted set of rolls.aluminum roll forming machine Each roll is designed to shape the metal to the desired cross section. The rolls can be simple cylindrical shapes, or complex shapes that are designed to fit the profile of the sheet metal.

The tooling used for roll forming can be expensive.aluminum roll forming machine Some companies opt for cladding parts instead, a cheaper solution that still results in the same quality and consistency of the final product. In addition, some companies use pre-punched holes to cut the weight of the final shape. These applications can limit the production rate of roll forming machines.

The cost of metal is another factor that may affect the pricing of a roll formed part.aluminum roll forming machine Aluminum prices can vary widely from one metal to the next. Roll formed aluminum pieces can be thin and lightweight, while other metals are more rigid and need to be cladded to reduce weight. Depending on the design of the final product, more bending stations are needed.

Aluminum, as well as Stainless Steel, is a malleable metal that requires careful control of the moving parts in order to produce the desired shape. The process also requires lubrication, which reduces friction and prevents tool wear. Roll forming equipment is capable of producing parts from materials that have a thickness as thin as 0.005 inches. In addition, it can shape painted steels and nonferrous metals.

During roll forming, metal coils can be as long as 30 inches. Typically, coils are shaped before entering the roll forming machine, and they can be tapered to make it easier to slide into the forming rollers. Once they are ready, they are fed into the uncoiler. In addition, some coils may have slots, holes, or slits, which must be added during the process.

Roll forming equipment can shape metals into nearly any shape. This includes complex cross sections, such as those produced using ferrous and nonferrous metals. In addition, this type of forming process can be integrated with other secondary processes, such as welding. It can also be used to shape metal that has a removable protective coating.

The speed at which the metal is rolled is important. Rolling equipment uses minimal bending pressure at each step, resulting in better control of the final shape. In addition, the process produces less scrap than other metal working processes. This lowers the cost of working with expensive metals. It also allows for greater flexibility. Some companies use CAD/CAM systems to optimize the forming process and reduce human intervention.
