Shot peening

Shot peening is a metalworking process used to modify the mechanical properties of metals and composites. It finds applications in various industries such as automotive, railway, aerospace, etc., for workpieces that need to enhance strength and durability.


  • To provide greater strength
  • Life extension
  • 100% repeatability of process


Shot peening is a cold machining process in which the surface of the workpiece is treated with an abrasive. Each bead acts like a small hammer, creating a small dent in the surface. With a high concentration of impacts, they are smoothed into a flat, solid surface. Consequently, a layer of compressive stresses forms on the surface, eliminating the possibility of the workpiece structure collapsing.
