Peening makes use of spherical media to ‘hammer’ the surface of a material. It’s a very effective way of improving the strength of a part. Bombarding it with media produces a compressive stress that improves strength by giving the material’s grain structure a shallower depth with a more random textured pattern.

The change to the surface structure makes it far less likely to fracture. Like all wet blasting applications, the flow of media over the component ensures a smooth consistent finish, especially compared with dry peening.

Numerous collaborative projects with our customers have helped us perfect peening by wet blasting.  Of particular note is the application of several wet blasting machines for peening fan and turbine blades for the aviation industry.

Our wet blasting systems offer excellent controllability, delivering a high quality consistent result every time. Leading aerospace manufacturers rely on our wet blasting systems for precisely these reasons
