Figure 1 – General scheme of the tutorial subject


In this tutorial a cold forged part is studied from the point of view of the tooling. The studied blow is a backward extrusion, and the main objective is to increase the tool life.

The studied die is the sliding die from the second stage (the spring has not been drawn).

The strategy used in this example is based on improving the design. The use of specialized Finite Element Analysis software to find out an optimum design is critical for this purpose.


Main goal of the tutorial: To show an example of Tool Life Optimization carried out with the support of finite element analysis.

Concerned issues:

  • Tool analysis.
  • Design modifications.
