Free Engineering Tool: Press Brake Bending Force Calculator
Stop guessing your tonnage. Stop relying on outdated, complex charts. Our free, instant calculator—developed by WEIYA's own factory engineers—gives you an accurate tonnage estimate for your air bending application. As a leading press brakes manufacturer, we provide the tools you need to get the job done right.

Understanding Your Tonnage Calculation
As a specialist manufacturer, we believe in empowering our partners. Here’s a brief explanation of the key factors in your calculation.
What is Air Bending?
This calculator uses the standard air bending formula, which is the most common and flexible bending method. It assumes the punch does not "bottom out" or "coin" the material.
The Importance of the V-Die Opening
The V-Die opening is the most critical factor. A good rule of thumb is 6x to 8x your material thickness (e.g., 8mm die for 1mm steel). Making the V-Die smaller will dramatically increase the required tonnage.
Material Factor (K-Factor)
Different materials have different tensile strengths. Stainless steel, for example, requires ~1.5x the force of mild steel, while aluminum requires ~0.5x. Our calculator automatically adjusts for this.
Now That You Know Your Tonnage, Find the Right Machine
Knowing your tonnage is the first step. The next is choosing a machine that can deliver that force reliably for a decade. Our press brakes are engineered with 1000kg heavier, annealed frames that guarantee they can handle their full rated tonnage without deflection, day in and day out.
