What is a "profile"?

Profiles are rod shaped products, used to retain a cross-section across their entire length. For example, tubes, window frames, bars, I-beams, T-beams or structural profiles. During their manufacturing process, particular care is taken to ensure linearity. Before their application, profiles need to be adjusted to fit the specific requirements.

If a profile is fixed onto the machine and bent, it would never be able to form into the desired shape, as it would just snap. This is particularly true for hollow profiles like tubes or frames of heat insulating windows. This bending process has to be conducted with a lot of direct power, but also allow for controlled straightening. Profile bending machines can achieve this. With these machines profiles are cautiously and precisely bent into the right shape.

How do profile and section bending machines work?

The standard design of a profile bending machine is the same between all the different manufacturers. They usually are made up out of three rollers, which in industrial settings, are hydraulically operated. There are also manually operated profile bending machines (i.e. those using jack screws).

These are primarily used for skilled crafts and trades. Automobile workshops use these manually operated profile bending machines to manufacture e.g. exhausts and to give the pipes characterises of their specific workshop. The construction of these machines is usually the same: two rollers lie in a row with the third roller staggered across them. The workpiece is then placed between the two linear rollers and the staggered roller. The rollers are put into motion using a button, where they then move on top of one another. A highly powered hydraulic machine is required for precise results. The bending process begins as soon as the rollers and the workpiece meet. This can be stopped automatically or manually. Finally, the rollers move away from each other and the profile has its new desired form. As an alternative to the three-roller design, there are also profile bending machines that use a especially custom made tool as the forming element. The profile is pressed into place using this machine. This process is commonly used in mass production. There is a large range of profile bending machines available. Profiles ranging from profile cross sections of a few millimetres in diameter up to pipelines with a cross-section of over two metres can be processed using these machines.

Working with a profile bending machine requires a lot of experience, unless it is for the mass production of small pieces. A certified qualification is not necessary, but unskilled workers must have intensive and supervised training. This is particularly important for complex forms or high-end products like tubes for pipelines.

Suppliers of profile bending machines

In the industrial context, well-known manufacturers are KNUTH, ROUNDO, VOORTMANN and THOMAN. Good machines for workshops and construction sites are available from O+P, GRANGIER CONSTRUCTEUR and NUOVA. Suppliers of machines for particularly large products are SUPERIOR and GENERAL DISCILLING
