Hydraulic Press Brake Tonnage Chart & Bending Force
| Thickness (mm) | V-Opening (mm) | Tonnage per Meter (T/M) |
|---|---|---|
| 2.0 | 16 | 17 |
| 4.0 | 32 | 34 |
| 6.0 | 50 | 48 |
| 8.0 | 63 | 63 |
* Data based on mild steel with tensile strength of 450N/mm².
Basic Bending Force Formula
For mild steel (450N/mm²), you can estimate the required tonnage with this formula:
P = (650 × S² × L) / (V × 1000)
P = Bending Force (Tons)
S = Plate Thickness (mm)
L = Plate Length (mm)
V = V-opening Width (mm)
*Note: For stainless steel, multiply the result by 1.5.
