How to transform the metal to make it more uniform and corrosion-proof. A necessary step to extend the life of the product and deliver a prototype that paves the way for its twin pieces.
Shot peening: more life to the metal.
After a jet of microspheres, metal is no longer the same. The shot-peening technique makes the surface less porous and eliminates post-welding oxidation. The piece is then protected from halos and future corrosion. And the contrast with the glossy surfaces is of confident effect.
