Rollformer or press brake? How to decide the right technology and maximize profit
Roll forming machines, press brakes, 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.
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, Dallan shows 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.
