The STRESSONIC® peen forming process is an innovative, high-performance technology providing an alternative solution to the hammer peening or pneumatic hammer. It is a mechanical impact treatment projecting needles (also called impactors) onto the surface of metal part.
The peen forming (or even ultrasonic needle straightening) operation changes the geometry of a metal piece to progressively reach the desired shape. It is a reliable and proven alternative to a hammer peening or pneumatic hammer, with much less impact on operator health.
SONATS has developed a portable shot peen forming equipment called STRESSVOYAGER® UNS (Ultrasonic Needle Straightening). This compact and lightweight device is ideal for improving productivity in your factories, allowing to straighten or mechanically form, directly on the jig.
