Laser Shock Peening and Laser Micromachining treatment on casting dies

Original language description

This technology aims to enhance the performance and durability of casting die, used in the production of aluminium castings. Laser Shock Peening (LSP) is applied to critical areas of the die to introduce deep compressive residual stresses, which slow down the propagation of cracks caused by cyclic thermal and mechanical loading, thereby extending the die's operational lifespan. Additionally, Laser Micromachining (LMM) is employed on the same areas to create microstructures that reduce the adhesion of aluminium castings to the die, minimising wear and facilitating easier release of the cast components. The combination of these two laser technologies is expected to significantly improve the durability of the casting die, reduce downtime caused by maintenance or replacement, and enhance the overall efficiency of the die casting process.

Technical parameters

The presented technology combines Laser Shock Peening (LSP) and Laser Micromachining (LMM) to extend the lifetime and improve the performance of casting dies. LSP introduces deep compressive residual stresses into the surface of thermally loaded areas, which improves resistance to crack initiation and propagation. LMM creates a fine micro-texture that reduces aluminium adhesion and helps the castings release more easily. The combination of these two laser-based surface treatments on a high-pressure die casting tool is innovative because it provides both mechanical strengthening and functional surface improvement without changing the tool geometry. To the best of our knowledge, this is the first reported application of the combined LSP and LMM technologies in aluminium high-pressure die casting. This novel integration opens a new path for improving the durability, surface quality, and productivity of dies used in demanding industrial applications such as components for electric vehicles.
