Roll forming is a production process used to form sheet metal gradually until it reaches your desired shape. JMC Equipment notes that although using a roll bender from Baileigh can produce the necessary parts for an automotive engine, the process itself goes through several complex stages.
But just how does it work?
The process Behind Roll Forming
The very process itself is a combination of different methods used to create the sheet metal forming process. It’s suitable for manufacturing constant-profile parts in a continuous form. Manufacturers can easily combine the process of roll forming with other methods, such as notching and embossing.
The process of roll forming takes a short time and less energy compared with extrusion. However, the process itself requires a large quantity of production to utilize the cost of investment fully.
According to Research Gate, the basic roll forming process is applicable to various automotive parts, such as car body and bumpers, ship construction, bicycles, and even beam members.
The Theory Behind Bending
The outer fibers tend to stretch better in actual bending compared with the inner fibers when it shrinks. The ductility of the sheet metal itself plays a crucial role in the bending process.
One can improve the bendability of a sheet metal by subjecting it to hydrostatic stress. The method tends to improve ductility, which makes that metal sheet more malleable to bending and rolling. Another method to improve bendability is by inducing compressive stress to the material.
Understanding how the roll bender works is a great way to be able to utilize the machine to your advantage fully. That’s why it’s always best to ask a company that has been around for several years to get more information on how automotive equipment is produced and distributed.
