Shot Peening

Our efficient shot peening service is for springs and other precision-engineered metal components. It is backed by over 40 years of technical know-how and expertise, along with rigorous ISO 9001 quality control.

What is Shot Peening?

Shot peening is the process of accelerating small, rounded particles (shot) at the surface of a component. The shot is propelled using air or discharged by centrifugal force from an impeller wheel.

When the shot particles strike a component’s surface, they cause the surface to deform plastically, with hammerhead like impressions into the surface. As a result, it increases the fatigue life of springs and other components.

One of the reasons for this increased life is due to compressive residual stresses imparted on the surface of the component, where the operational stresses are at a maximum.

The Benefits of Shot Peening

Improves the lifespan of a component

Reduces the risk of surface cracks

Helps prevent failures, improves performance

Improves compressive stresses

Removal of burrs, metal flashing and scale
