What SONATS does

SONATS is a French industrial company specializing in mechanical surface treatment by impact, built around its patented STRESSONIC® ultrasonic technology. Founded in 1992 and headquartered in Carquefou, France, the company designs and manufactures ultrasonic shot peening (USP) systems, ultrasonic impact treatment (UIT/HFMI) equipment, and ultrasonic forming/straightening systems, complemented by a certified residual stress measurement laboratory. Its technology activates shot media through ultrasonic vibration rather than conventional air or turbine propulsion, delivering measurably tighter process control (±1.8mmA Almen precision versus the ±3.8mmA SAE AMS standard) and real-time amplitude monitoring per SAE AMS 2580. The product portfolio spans portable handheld units (NOMAD, STRESSVOYAGER® USP), semi-mobile benches, and fully automated robotic cells, with current installations capable of up to 500,000 parts/year per machine.

The company operates a hybrid business model combining capital equipment sales, subcontracting and series production services from its Carquefou workshop, certified laboratory and testing services (XRD, hole-drilling per ASTM E837, contour method, eddy current), and training/technical support. Pricing is quote-based and undisclosed. Sales are enterprise-led, with technical sales engineers engaging engineering and procurement decision-makers at major OEM accounts across aerospace (Airbus, Safran, Dassault, GKN Aerospace), automotive (Daimler, Toyota, Volvo, Renault F1), energy/nuclear (GE, Mitsubishi Heavy Industries, Areva, Alstom, MTU), railway (SNCF), heavy industry (Caterpillar, John Deere, ArcelorMittal), defense (Liebherr), medical, and civil infrastructure. Go-to-market relies on industry trade shows (Paris Air Show, Schweissen und Schneiden, EUROSATORY), direct technical sales, and on-site service teams.

Since January 1, 2020, SONATS has operated as a trademark and subsidiary of EUROPE TECHNOLOGIES SAS, a diversified French industrial group, following a merger-absorption designed to enable larger-scale project bidding and cross-skill capability expansion. Despite the consolidation, SONATS maintains its brand identity, ISO 9001 and EN 9100 certifications, and SAFRAN laboratory qualification, with commercial presence documented in France, Germany, the United States, and Singapore.
