Applications Across Critical Industries
Shot peening is a critical surface treatment process used across multiple industries to improve fatigue strength, durability, and overall component performance. The automotive sector represents approximately 70% of global demand, with applications including valve springs, suspension components, gears, shafts, crankshafts, and connecting rods.
In aerospace and defense, shot peening is essential for enhancing the reliability of landing gear, airframe components, turbine parts, and structural elements operating in demanding environments. The process is also widely used in the energy sector for oil and gas equipment, power generation components, and wind turbine gearboxes.
Beyond these industries, shot peening plays an important role in general manufacturing for surface preparation, cleaning, deburring, and blast finishing operations.
