The STRESSONIC® process is an innovative, high-performance technology providing an alternative to conventional shot peening: ultrasonic shot peening. This is a cold impact mechanical treatment that projects media against the surfaces of metal parts by means of ultrasonic wave frequency.
Ultrasonic shot peening improves the fatigue strength and corrosion resistance of metal parts subjected to high tensile stress. Ultrasonic shot peening can improve fatigue strength up to 1000%.
In new applications, SONATS technicians and engineers make a complete study of the characteristics of both the part and the variables of the shot peening treatment, to determine the most appropriate solution depending on the customer objectives and requirements.
SONATS has developed a portable ultrasonic shot peening machine, the STRESSVOYAGER® USP. This equipment is used at our workshops or at the customer site to treat complex metal parts without disassembly of the surrounding elements and under optimal safety conditions.
SONATS develops automatic shot peening solutions, equipped with STRESSONIC® technology, to improve productivity by reducing the shot peening cycle time and the risk of human error via real-time control of parameters.
SONATS provides ultrasonic shot peening services at its subcontracting workshop in Carquefou (44, France), for offloading or series production.
Nanocrystallisation is a shot peening process for the treatment and pretreatment of metal surfaces.
SONATS, the French distributor of Electronics Inc (United States), Toyo Seiko (Japan) and Shockform Aerospace (Canada), provides a wide range of equipment for shot peening, flapper peening and coverage rate analysis.
