Automated Shot Peening & Shot Blasting Machines
Shot peening is used to finish metal parts that require increased wear and fatigue properties. In the process, shot bombards the metal part, creating small dimples in the surface.
The dimples cause compression stresses in the surface of the part, increasing the metal's resistance to cracks, fatigue, and corrosion. Shot peening is used for critical, high-wear components such as gears, shafts and metallic skins for advanced aerodynamic products.
Engineered Abrasives® manufactures custom shot blasting machines that are designed to meet the specific requirements for your application. Our experienced engineering staff will work with you to design a custom shot peening machine for your process and help you select the best media for your finishing requirements.
