Press capacity calculation tool

Sheet metal bending is one of the most used sheet metalworking services. A lot of press capacity is needed to bend a metal sheet by a bench press. It is necessary to calculate the needed press capacity to avoid damages to the machinery.

Calculation tool for air bending

How to use the tool

  1. Choose the desired material.
  2. Enter the length of the material, thickness and the width of the die.
  3. The width of the die must amount at least 8 times the value of the material thickness.
  4. Click on Calculate.

Bending Force

Calculate the required bending force for different materials

The calculation tool was programmed with best care and attention. For all that Rime does not guarantee the correctness of the calculation result!

The tool is using this formula: F = 1.42 * L * Rm * t2 / W

  • F = Press capacity
  • L = Material length
  • Rm = Tensile strength
  • t = Material thickness
  • W = Width of the die (Standard: 8 x t)
