We offer air and wheel blast systems for peening high stress parts like gears, springs, drive shafts, axles and more. Round abrasives such as cast steel, ceramic, glass, and stainless steel shot are used to create uniformed compressive stress layers to prolong service life and reduce part failure. Peening also straightens parts that have been bent during heat treatment and machining.
Other benefits of Peening
Offsetting tensile stresses and changes in tensile strength due to grinding and chrome plating
Reducing porosity in castings that could lead to leakage of fluids
Improved oil retention on pistons, cylinders, and bearings due to small indentations created by media
