Photo Etching

Advantages of chemical etching process:

  • Achieving complex shapes with tight tolerances for samples or series
  • Unchanged base material's characteristics such as mechanical, electrical, and magnetic properties
  • Burrs and stress free, no breaking point, no heat-affected zone
  • Low tooling costs
  • High flexibility in case of design modification
  • Wide range of metals available in stock

Advantages of electroforming process:

  • Unrivalled micrometric precision
  • Extremely complex shapes with very low thickness
  • Very narrow aperture achievable
  • Burrs and stress free, no breaking point, no heat-affected zone
  • Low tooling costs
  • Black surface treatment available, dedicated to optical applications
