A patented breakthrough in metal surface engineering with a unique industrial impact.
A plasma discharge inside the PSP device generates a high pressure pulse that accelerates a solid impactor beyond 6000 m/s.
On impact, it produces controlled plastic deformation at the micron scale.
The resulting shockwave propagates into the bulk material, imparting compressive residual stress to a depth of 1+mm per application layer.
PSP runs cold, carried by a standard industrial robot arm.

Generate
01
A plasma discharge accelerates a solid impactor beyond 6000 m/s. No laser, no water, no dedicated building needed.
Strike
02
The impactor hits the metal surface. A shockwave propagates into the depth of 1+ mm.
Strengthen
03
Compressive residual stress is imparted into both surface and sublayer.
Residual stress profile

Device cost recovery is a matter for your business case — it depends on part value, replacement cost, and annual volume.
Shock vs. shot peening. Is there a difference?
There is, a massive one.
Shock peening utilizes shockwave, while shot peening means blasting particles. Shockwave delivers high magnitude residual compressive stress into exceptional depth up to 1+ mm per one application layer.
