Shot Peening

Shot peen, a cold-working metal process, is performed by directing a controlled stream of round particles (shot) against a metallic surface, creating a compressive layer in that surface. While the primary purpose of this layer of compressed material is to provide resistance to fatigue cracking, the consequential work hardening of the surface can provide the added benefit of resistance to fretting and wear. To accurately repeat this process requires a heightened degree of control and precision.

MIL provides the shot peen process to accompany our other capabilities, serving the aerospace, medical, and power generation industries. We currently have two machines online with additional capacity forthcoming.
