Roll formed sections have an advantage over extrusions of a similar shapes. Roll formed parts are generally much lighter and stronger, having been work hardened in a cold state. Another advantage is that the part can be made having a finish or already painted. Labor is greatly reduced since volume is a major consideration for choosing the roll forming process.
Roll forming machines are now being produced so that for similar products such as stud and track profiles, a new set of profile rolls is not required. This is achieved by the mill being split along its center line and the web, flange and ear sizes are set using a control panel which moves the mill rafts centrally to increase or decrease the aforementioned features.
Roll forming lines can be set up with multiple configurations to punch and cut off parts in a continuous operation. For cutting a part to length, the lines can be set up to use a pre-cut die where a single blank runs through the roll mill, or a post-cut die where the profile is cutoff after the roll forming process. Features may be added in a hole, notch, embossment, or shear form by punching in a roll forming line. These part features can be done in a pre-punch application (before roll forming starts), in a mid-line punching application (in the middle of a roll forming line/process) or a post punching application (after roll forming is done). Some roll forming lines incorporate only one of the above punch or cutoff applications, others incorporate some or all of the applications in one line.
While dealing with manufacturing, there are always things to be considered such as lubrication, the effect of the process on material properties, cost, and of course safety. Lubrication provides an essential barrier between the roll dies and the workpiece surface. They help to reduce the tool wear, and allow things to move along faster. This table shows the different kinds of lubricants, their application, and the ideal metals to use them on.
Roll Forming is the most economical choice for many companies that look to streamline their production and reduce overall cost. The high-speed continuous nature of roll forming is especially beneficial for large volumes.An experienced Custom Roll Former will incorporate a number of secondary operations in one line. Savings are realized through the need for fewer component parts, fewer post-production operations and reduced manufacturing cost.
The effects of the process on the materials properties for this process are very minimal. The physical and chemical properties virtually have no change. But the process may cause workhardening, microcracks, or thinning at bends when discussing the mechanical properties of the material.
The cost of roll forming is relatively low. Some things to be considered when calculating the cost of the process are setup time, equipment and tool costs, load/unload time, direct labor rate, overhead rate, and the amortization of equipment and tooling. Safety is also a bit of an issue with this process. The main hazards that need to be taken into consideration are dealing with moving workpieces (up to 800 fpm), high pressure rolls, or sharp, sheared metal edges.
A custom roll former can deliver finished shapes, cut to exact length for assembly in your production. This frees up valuable manufacturing space in your plant and completely eliminates scrap loss. By eliminating secondary operations, labor costs are also greatly reduced. All industries can benefit from the flexibility of roll forming. Many companies that use roll formers do so because they require consistent adherence to close tolerances.
