Die Life Enhancement

Shot peening is a cold working process used to produce a compressive residual stress layer and modify the mechanical properties of a component. It entails impacting a surface with shot, applying sufficient force to create plastic deformation.

The process is typically used for components to increase fatigue strength and resistance to stress-corrosion cracking for parts such as axles, springs (helical, torsional and leaf), gears, shafting, aircraft landing gear, structural parts, and similar items but usage is not limited to such applications.

Sinto has developed proprietary surface enhancement peening processes to improve the service life of your dies. The processes have proven to increase resistance to stress corrosion cracking and improve flow characteristics. Please contact us to discuss your needs.

FEATURES:

  • D – SCC is our proprietary surface modification process for improving resistance to stress corrosion cracking (SCC).
  • Sinto Surface Technologies’ D-SCC process for die cooling holes has shown die life improvements 3 times greater that dies that have not been treated with our process.
  • Less down time – increased productivity
  • Reduced maintenance and die cost
