Most failures attributed to cyclic fatigue or stress corrosion begin with tensile stresses and microscopic cracks created during grinding, machining, forming or casting of a part. The negative effect of these cracks can be eliminated or minimized through the process of shot peening.
While shot peening alters sub-surface mechanical properties, blasting alters only the surface. Shot blasting delivers superior results to parts for a variety of metals requiring a specific micro finish.
Godfrey & Wing provides unmatched attention to detail for masking, part handling, equipment and media maintenance. This allows for repeatable and reliable results on the most sensitive applications.
Godfrey & Wing offers the right combination of equipment, media and expertise to meet the most stringent specification, quality and delivery requirements.
