Shot Peening

Increases strength and durability!

Shot Peening is nothing new to Avcorp Industries. We design, fabricate, and assemble metal, composite, and plastic components/ structures for many of the world's leading aircraft manufacturers. Shot Peening is one of the services we provide. Our Shot Peening process utilizes both compressive stresses and cold working to deliver materials of the highest quality and strength.

Although the process of Shot Peening has evolved and become very technical, Shot Peening still employs the age-old principles of pre-stressing and work-hardening the product to create a harder and more durable material.

Today, Shot Peening involves bombarding a material with small spherical media called shot.

Each piece of shot is the modern day version of the hammer/ stone used in the past. As the Shot Peening is performed, the atoms on the surface of the metal become crowded and try to restore the metal's original shape by pushing outward. This pulls the atoms in the deeper layers towards the surface, which resist the outward pull, thereby creating internal tensile stress that keeps the part in equilibrium with the compressive stress on the surface. The tensile stresses, resulting from Shot Peening, deep in the part are not as problematic as tensile stresses on the surface because cracks are less likely to start on the interior.

Avcorp is pleased to announce that our Shot Peening is approved for Bombardier Specifications MPS185-2.
