Shot Peening

Increase fatigue life of
components with shot peening.

What is Shot Peening?

Shot peening is a cold-working process used in manufacturing and engineering to enhance the mechanical properties of metal components. It involves bombarding the surface of the material with small, rounded particles (shot) to induce compressive stresses, improving the component’s fatigue resistance and extending its lifespan.

Shot Peening at Vibra Finish

Shot peening is a cold working process that involves impacting a component with steel shot or ceramic beads to create beneficial residual compressive stresses. This helps increase the fatigue strength and durability of the component, increasing its resistance to fatigue cracking. We have the expertise and equipment to provide high-quality shot-peening services for a variety of components from a wide range of industries and specifications.

Increase fatigue life of components with shot peening.

Increased Fatigue Life

Shot peening is the most efficient technique for maintenance costs reduction. Machined components present tensile stresses at the surface, which promote fatigue crack initiation. On the contrary, shot peening creates compressive stresses on the surface of the component, increasing its resistance to fatigue failure. This significantly increases the component’s service life and reduces the need for frequent replacements.

Improved Strength

Components that undergo cyclical loadings, such as springs, shafts, transmission gears, and control surface components, benefit from the residual compressive stress layer imparted during shot peening.

Cost-effective Solution

Shot peening is a cost-effective way to improve the performance and durability of your applications. By extending their lifespan, you can save on frequent replacements and repairs.

Versatile Applications

A wide variety of metal, alloy, superalloy components can be shot peened, making it a versatile solution for a variety of industries such as aerospace, automotive, and advanced manufacturing.

Frequently Asked Shot Peening Questions

What types of materials can be shot peened?

Shot peening can be carried out on a variety of components manufactured from steel, aluminum, titanium, and their alloys. Vibra Finish technicians are experienced in identifying certified shot peening specifications from our customer RFQs and can provide customized shot peening services appropriately.

How does shot peening differ from other surface treatments?

Unlike other surface treatments that focus on improving a part’s appearance or corrosion resistance, shot peening is primarily used to increase its strength and durability. By creating compressive stresses, shot peening can significantly improve the performance of a part. Shot peening is the most cost-efficient and versatile surface treatment for this purpose.

Is shot peening environmentally friendly?

Yes, cold working processes like shot peening are environmentally friendly as it does not use harsh chemicals or emit harmful pollutants. Shot peening uses media re-circulating in closed loop so that no product is wasted for the treatment. At Vibra Finish, we are committed to sustainable practices and strive to minimize our environmental impact in all our processes.
