Micro peening

The method

Micro peening in the plastics manufacturing

Micro peening of mold inserts for plastics manufacturing means, that furrows, grooves or the so called “white zone” of the tools` interior surface will be compressed in the range of µm and the “white zone” will be skimmed. The removal rate of the sink erosion, determines the thickness of the “white zone”, ranging from 0 to 0,1mm. This should be considered when eroding.

The complete removal of the “white zone” and the surface compression leads to an improved surface roughness. By using exactly defined particle sizes at the micro peening process, the surface roughness will be less than 0,6 µm.

 

Micro peening of copper electrodes offers the following benefits:

  • Smoothing with shorter duration
  • Treatment of the insert surface with micro peening only (no manual work)
  • Reduction of the polishing operation time by approximately 50%

 

By using specific granulations it is possible to apply an additional non-stick coating. This creates an especially smooth (low-friction) surface which opens up significant advantages in the manufacturing process:

  • Enhanced material flow
  • Enhanced end forming
  • Use of release agents often not necessary.
