High speed and highly controlled, the process of shot peening has many similarities to the aerospace, automotive, and aviation components it is used on. The machines require absolute precision and reproducibility much like the components they are preparing for long life and changing loads.
Shot peening is a special shot blasting process in which spherical blast media is thrown at the surface of metallic work pieces. The impact energy of the pellets “cold forms” the upper layers of the metal similar to hammering and forging processes.
Important factors that should be considered in the selection of any blast mediafor a particular application is the material and chemical composition, its hardness, its density, its shape, screen size and last but not least, the hardness of the component to be blasted.
