Airless shot peening has become a cornerstone treatment for extending component life in aerospace, automotive, railways, heavy engineering, and energy sectors. As fatigue failures get costlier and quality expectations soar, manufacturers across the country are moving from basic blasting to controlled airless shot peening for predictable compressive stresses and repeatable results.

What is Airless Shot Peening?

Shot peening is a cold working process that bombards the surface of a component with small spherical media (steel shot, stainless shot, or ceramic) to induce a uniform layer of compressive residual stress. This stress layer dramatically improves fatigue strength, resists stress corrosion cracking, and reduces the likelihood of micro-crack propagation.

Unlike air-driven systems that use compressed air nozzles, airless shot peening machines use high-efficiency centrifugal blast wheels to accelerate media. The wheel blades sling shot at controlled velocity and coverage onto the work surface. The result: higher throughput, lower operating cost per part, and a compact footprint—ideal for high-volume Indian manufacturing lines.
