Shot Peening Effect
Reinforcement of a welded part with the shot peening effect increases strength by imparting residual stress to the surface of the workpiece through the high speed impact of the needles. Highly suitable for effective reinforcement of deteriorated welded parts.

Fully Automatic System
The only unit of its kind on the market without springs. This means no springs to break…no irregular power… and the advantage of low air consumption.
