Air tight shot-peening

With no risk of losing shot peening media, our ultrasonic shot peening treatment can be directly performed on structure assemblies (transportable subassemblies, on-site treatment, non-transportable parts, and ex-situ treatment).


The hermetic seal chamber enables technician to use very low shot peening media quantity during  the treatment. This unique shot peening process with very high quality media allows us to reach unrivalled surface quality – low roughness.



Localized shot peening

No masking and no bagging of your parts. Our process saves time. Our treatment cycle are reduced and so are our lead-times.
