Various types

The roll forming process is a popular manufacturing method used in the production of various kinds of products. They are great for producing parts with fine details and excellent finish. They also require little or no finishing work and are fast in their production rate. A roll forming machine is an excellent choice for producing parts of any length. However, the high set-up costs of this process may limit their use in the production of certain parts.

Various types of rolling forming machines include single-head, double-headed, and rafted. These machines feature two sets of rolling shafts and housings with different widths. Depending on the thickness and material thickness of the components, the speed can range from five to 500 feet per minute. The rates of roll forming lines are also affected by punching applications. To make the most efficient use of these machines, you should select a machine that is well-suited for the specific requirements.

The cold roll former is an effective machine for producing various types of metal profiles. A cold roll former can also perform additional operations, such as cutting, punching, and label printing. Cold-rolled steel is more durable than hot-rolled steel and prevents additional costs associated with heating and cooling. Its numerous applications make it a valuable addition to any manufacturing facility. If you’re interested in using rolling forming machines to produce metal products, contact us today!

Modern roll forming machines are equipped with programmable logic controllers that ensure accuracy and precision. They also have laser and TIG welding capabilities, which reduce the energy efficiency of the machine and eliminate a step of the manufacturing process. There are many types of rolling forming machines available in the market today. Once you choose the right one for your needs, you’ll be surprised at the variety of applications it can perform.

Operating procedures

Successful roll forming is highly dependent on a combination of factors, including the material properties, tooling set up, and machine operation. However, some issues may occur, and a systematic approach can help identify the root cause of the problem. The following are some operating procedures for rolling forming machines. In the first place, it is essential to identify the tooling set up. To avoid common problems, make sure that the tooling is properly aligned.

When using a rolling forming machine, make sure that you have trained personnel who understand the workings of the machine. Then, ensure that all push buttons are lit. Once all of the push buttons are lit, the machine is ready to begin its process. Then, follow the procedures to ensure that you do not disturb the machinery while it is running. These procedures will ensure that the machine is operating safely and efficiently. If you’re not trained to operate a rolling forming machine, it could result in catastrophic results.

Before operating the rolling forming machine, measure the thickness of the material you’re going to be rolling. Even though a sheet of material is labeled as “16 gauge,” that doesn’t mean it’s exactly 0.060 inches thick. The gauge refers to a range of thicknesses, so your actual material is a little thicker or thinner than this number indicates. Once you know this, you can make an accurate estimate of the capacity required for a particular part.

Once you’ve made sure that the tool gap is set correctly, you can start the forming process. You can adjust the gap between the rolls using the top roll. This will change the amount of forming pressure applied to the metal. When setting the gap correctly, you can adjust the gap between the rolls and adjust the blade and die to achieve the desired final dimensions. Afterward, you can make final adjustments to get the part that you want.

Materials used

Roll forming is the process of transforming metal sheets into various section shapes. The sheet metal is fed into the machine and then undergoes various steps of processing, such as the cut off and tuning stand. The final shape of the section drawing is achieved. This process is highly efficient and can produce complex cross sections, such as helical and spiral profiles. In some cases, it is possible to produce parts of any length using the same tooling.

The common materials used for roll forming are coiled carbon steel and stainless steel. Copper and aluminum are also used. Surface treatments can be added before forming, which enhances the manufacturing process efficiency. Light gauge materials can be pre-painted to increase the aesthetic value and reduce corrosion protection. However, heavy gauge materials will negatively impact corrosion protection. Once formed, the raw material will become exposed, and it will be necessary to apply protective coatings and finish to ensure a good look and durability.

Roll forming is a metal fabrication process that adds strength and rigidity to lightweight materials. Whether it is a tool for industrial purposes or for making household appliances, roll forming is an efficient way to manufacture high volumes of metal components. Many different industries use this technique to create various shapes. Some of these materials are highly corrosion-resistant and contain a high percentage of chromium. Stainless steel is also highly stain and corrosion-resistant. Aluminum is a lightweight, pliable metal that has excellent corrosion resistance.

Other materials used in a rolling forming machine are the slack loop and strip accumulators. These two components allow the coil strip to stop at a certain position for the pre-punch press stroke. These are used in high-speed operations that require precision timing to feed another segment of “slack”.


There are many variables that can influence the cost of a rolling forming machine. Tooling is a huge cost driver. In order to save money on rolling forming, cutting costs requires more than cutting corners; it is essential to take this into consideration throughout your project. The following are a few things to consider. Firstly, make sure that the machine has enough forming stations to shape the product that you need to form.

Consider leasing if you have limited capital and can’t afford a full purchase. A leasing contract will allow you to upgrade your equipment every few years. If you don’t need it immediately, it may save you money in the long run. A lease contract is usually between 24 and 72 months and allows you to take advantage of tax incentives for upgrading your equipment. You can also customize the machine to suit your specific business needs. However, make sure to check the availability of replacement parts.

The production rate of a rolling forming machine will depend on the thickness of the material to be formed, the number of stations required, and the bend radius. For instance, a 50-times bend radius low carbon steel can be formed at a rate of 85 feet per minute through eight stations. A similar line of 22 stations can produce up to 500 feet per minute. The production rate may be limited by punching applications.

The speed of the roll forming process means that the cost of labor is lower than the cost of other forms of metal working. Furthermore, there is no need to heat the metals before the forming process. The lower scrap also reduces the cost of working with expensive metals. Another advantage of roll forming is the ability to retain residual stress and weld seam control. This means that the process is more repeatable than many other forms of metal bending.


Among the various types of defects present during the rollforming process are scabs, which are raised, irregular ridges on the surface of the metal casting. Scabs are a result of sand crusted over the surface of the mould. Grinding and other processes will remove them. Indentations, meanwhile, are normal depressions or indentations on the sheet surface. There are many names for these imperfections. We’ve already discussed buildup on idler and chill rolls. We’ll look at the other types and discuss their respective processing conditions.

The radius of a bend in a sheet of metal is largely determined by the ductility of the metal. Consequently, a roll forming machine can produce bend radii that are smaller than the required radius. Similarly, absolute sharp corners can be developed by reducing the metal thickness. However, this isn’t a recommended design approach, as it limits the life of the creasing roll and weakens the section.

Another kind of imperfection is an edge wave, which is a small bow. This is caused by a large amount of deformation concentrated in one local area. Other types of imperfections are wavy edges, curved surfaces, and edge waves. Imperfections on a roll forming machine may be caused by a misaligned entry guide or a malfunctioning tooling. To reduce these problems, you must conduct testing before rolling forming.

The materials used for the tooling on a rolling forming machine will also affect the maintenance practices. Some tools are heat-treated, whereas others are not. If the tooling is made of a pre-painted material, it might not be suitable for lubricants. Hence, vanishing oil is the best choice. Coolants can also damage pre-painted parts. And as with any part, lubricants can also affect the quality of the finished product.
