Extrusion Force Calculator


Calculating extrusion force is crucial in various industries, especially in manufacturing processes involving plastic or metal extrusion. This article provides an efficient extrusion force calculator, simplifying the process for users.

How to Use

  1. Input the required parameters such as material properties and geometrical dimensions.
  2. Click the “Calculate” button to obtain the extrusion force.
  3. Review the calculated result displayed below the input fields.


The formula for calculating extrusion force is:


  • F is the extrusion force.
  • K is the shear strength of the material.
  • L is the length of extrusion.
  • D is the die diameter.
  • h is the thickness of the material.

Example Solve

Let’s consider an example where:

  • Shear strength (K): 150 MPa
  • Length of extrusion (L): 100 mm
  • Die diameter (D): 20 mm
  • Thickness of material (h): 5 mm

Substituting these values into the formula:

So, the extrusion force is 3000 Newtons.


Q: Can this calculator handle different units?
A: No, this calculator assumes consistent units for all inputs. Make sure to use the same units throughout.

Q: Is the shear strength constant for all materials?
A: No, shear strength varies depending on the material. Refer to material specifications for accurate values.

Q: What if I have irregular geometrical shapes?
A: This calculator assumes simple geometries. For irregular shapes, consult specialized software or professionals.


This extrusion force calculator provides a convenient tool for engineers and professionals involved in extrusion processes. By inputting the necessary parameters, users can quickly obtain accurate extrusion force values, aiding in efficient manufacturing operations.
