Liming Stamping Roll Forming Machine company has over 24-year experience on producing Roll Forming Machine in forming industry. With rich experience and advanced technology, Liming company sells over 1000 machines every year to more than 36 countries.

Roll forming machine, press brake, wing and panel bander are the main technologies used to form metal profiles: the technologist’s experience plays an essential role in deciding which one to choose and has a profound influence on the results and profits generated with the production.

A simple formula can help calculate the number of produced parts N that justify the investment in roll forming tooling, using just three pieces of information.

Here it is:

N = 3600 * (cost of roll forming tooling) / [(hourly cost of press brake) * (cycle time in press brake)]

The formula has been customized for comparing roll forming machine and press brake, but it can be easily transformed for wing and panel bender.

In this article, I will show how to get to this formula and how to use it in the specific case of roll forming and press brake. Finally, some case studies to confirm the results.
