Ultrasonic Peening Solutions – Metal Improvement

The STRESSONIC® technology

Our sister company SONATS created the STRESSONIC® peening technology to offer an alternative to conventional methods with more control, and consistency. This technology can be used manually with a portative equipment and automatized with production machine or robot. Three different processes have been developed using the STRESSONIC® technology: Ultrasonic Shot Peening (USP), Ultrasonic Peen Forming (UPF), and Ultrasonic Impact Treatment (UIT). Empowering Technologies experts will advise you on the choice of technology according your application.

Ultrasonic Shot Peening

Shot peening is a process used to induce superficial compressive stress, and to modify the mechanical properties of metals. Ultrasonic Shot Peening uses a vibrating surface to propel media to a metal part. This technology aims to create consistent dents superficially improving mechanical properties. Our ultrasonic technology improves fatigue resistance, shortens treatment cycle and can be performed without dismantling and bagging the part.

Ultrasonic Peen Forming

Mechanical needle straightening and peen forming operations generally means finishing the shape of a component or a metal structure. Our ultrasonic technology is used to perform this metal forming and straigthening. Ultrasonic Peen Forming uses a vibrating surface to propel multiple pins. This technology aims to shape and form panels.

Ultrasonic Impact Treatment

Ultrasonic Impact Treatment (also called HFMI – High Frequency Mechanical Impact) uses a vibrating surface to propel a single pin. This technology aims to enhance critical areas with plastic deformation. The creation of superficial compression, by peening, due to the impact of the needles on the material also makes it possible to improve the resistance for stress corrosion cracking.
