Laser Shock Peening treatment on forging dies

Original language description

The application of LSP to forging dies represents a groundbreaking advancement in tool surface treatment technology. To the best of our knowledge, this is the first successful implementation of LSP on this type of forging die globally. The novelty of this approach lies in its ability to introduce deep compressive residual stresses into the surface of the forging die, significantly enhancing its resistance to fatigue cracking, with the stress profile extending into the material depth as shown in the attached graph. Unlike conventional surface treatments, LSP achieves this without compromising the material properties or geometry of the tool. This innovative application not only extends the operational life of the forging die but also demonstrates the potential of LSP to revolutionize the durability and performance of industrial tools in demanding environments.

Technical parameters

The aim of this proven technology is to enhance the performance and longevity of forging dies with Laser Shock Peening (LSP). Forging dies are highly stressed tools frequently subjected to fatigue cracking. These fatigue cracks necessitate the replacement of the dies, resulting in decreased productivity and increased manufacturing costs. LSP surface treatment introduces compressive residual stresses into the surface of the component, which slows down the propagation of cracks or even completely eliminate crack initiation. Consequently, the resistance of forging dies to wear and tear is improved, extending their operational life and reducing the frequency of replacements.

Economical parameters

Based on the real demand for prolonging the life of tools, the potential of which is described in the marketing study, we assume application in forges such as Nittan, Eaton or Strojmetal. Already during the development itself, there is cooperation with the named companies, and the case study of the project will be carried out on selected dies from companies production.
