Optimal abrasive




Surface modification Shot Peening

Shot peening is used to harden or shape the surfaces of a workpiece (peen forming). The abrasive particles are rounded due to the hammer effect. Compressive residual stress is induced in the workpiece, so that the initiation of fatigue cracking is significantly delayed. This means more durable components, enhanced fatigue strength under constantly alternating stress conditions and higher dynamic strength in combination with lightweight materials.

  • Hardening
  • Shaping

Surface cleaning Shot Cleaning

Surfaces which are blasted with round or angular abrasives are cleaned and prepared for downstream coating processes. Descaling and deburring of cast or forged components, descaling of and rust removal from steel profiles or the removal of old paint and other coatings are just a few typical examples. Especially when angular abrasives are chosen, shot cleaning alters specific properties of the surfaces. It can be used to roughen brake pad mounts, for instance, create a positive fit with brake pads or roughen surfaces in prepara- tion for a subsequently applied metallic coating, e.g. prior to galvanising.
