Maybe you are a sheet metal processing factory and now you need to buy a press brake.
You may wondering how big press brake do I need? And you urgently need to quickly calculate the required bending tonnage.
By using the press brake tonnage calculator (also known as bending load calculator) below we have made for this purpose, you only need to enter the sheet metal thickness, the bending length and our recommended vee opening width, the calculator will show the required bending force.
Of course, if you want to know exactly how the tonnage of the press brake is calculated, you can refer to this article.
It details how to get the required press brake tonnage in three different ways.
Let’s start by using the press brake tonnage calculator that we have made for you.

Press brake tonnage calculator
You can use the following press brake tonnage calculator to calculate the required bending force for your sheet metal bending.
The unit is in metric.
New tonnage calculation method
If the width-to-thickness ratio V/S is not equal to 9 and the radius-to-width ratio is not equal to 0.16, the above calculator will no longer be applicable.
