Required Force
22.4 US tons
Required Force199.5 kN
Required Force20.3 metric tons
With 20% Safety Margin26.9 US tons
Tonnage per Meter22.4 tons/m
Recommended Die Opening24 mm

How to Use This Calculator
- Enter material thickness and bend length (inches).
- Set the die opening (V-width in inches) -- typical rule: V-width = 8x material thickness.
- Enter tensile strength (tons/in2) -- mild steel: 25, stainless: 45, aluminum: 15.
- Review required bending force (tons) and recommended press brake minimum tonnage.
- Select a press brake with at least 20% more capacity than the calculated force to account for variation.
