Automotive / Medical / Tooling



This industry always push the limits of strength and performance of materials to ligthen the vehicles for cost savings and lower fuel consumption. Enhancing the fatigue life performance of metal component allows industrials to design ligther engines or other equipments.

Typical Automotive applications of Ultrasonic Shot Peening include :

  • Engine cradles
  • Injectors
  • Cam shafts
  • Crank shafts and counterweights
  • Connecting rods
  • Yokes
  • Gears and Gear box
  • Chassis parts
  • Brake drums
  • Aluminum wheels
  • Flywheels

When introducing smart solutions for enhancing life and healthness of people, Reliability and Security are the primary concerns of this industry.

SONATS Ultrasonic Shot Peening solutions are well adapted thanks to its high quality and complete process control.

Typical Medical applications of Ultrasonic Shot Peening (USP) Stressonic® include :

  • Surgery instruments
  • Orthopedic prosthesis  and implants (Hip, Knee, Spine, Tibial…)




Some tooling devices are submitted to rough conditions and consequently need to be hardened.
Several technologies (chemical, thermical or mechanical) exist and could be used and possibly combined for part hardening parts. Ultrasonic Shot Peening is an efficient and proven solution and well-adapted for uniform treatment of complex geometries with a smooth surface finish.

Typical Tooling applications of Ultrasonic Shot Peening (USP) include :

  • Drilling bits, chisels
  • Sawing, Cutting
  • Fastening
