BEIGEMA sizing tool
Press Brake Tonnage Calculator
Estimate the force for a conventional air bend before comparing press brake models. Enter the same material, thickness, active bend length and V-die opening you will use on the shop floor.
Start with the part. Capacity comes from the material and bend—not the machine name.
02 / Review estimate
Calculation result
Estimate for conventional air bending only. Verify actual tensile strength, tooling load, off-centre limits, working length and forming method before production.
Before selecting a machine
Use the estimate as a starting point
The tool separates the physical bending estimate from the planning allowance, so the two numbers are not confused.
Included in the estimate
- Material tensile-strength factor
- Thickness squared, active bend length and V opening
- Metric and imperial force conversion
- A separate, user-selected planning allowance
Requires engineering review
- Bottoming, coining, hemming, offsets or multiple bends
- Tooling load per length and short-segment concentration
- Off-centre bending, high-strength plate and unusual radii
- Final machine model, stroke, daylight and duty cycle
Reference methods: Bystronic tonnage guidance, Wilson Tool air-bending chart, and CINCINNATI load calculator.

Send the part drawing to BEIGEMA
Include material grade, thickness, bend length, V opening, flange geometry, required tolerance and production volume. BEIGEMA can then check capacity, tooling and working length on the same requirement.
