Etching technology

Expertise gained from decades of experience

Etching technology is a traditional and purely manual process for applying structures
to metal surfaces bymeans of chemical reactions. This technology is used in particularin
the further processing and surface finishing of plastic injection moulding toolsmade of
stainless steel or – to a limited extent – non-ferrous metals.  Skilled craftsmanship,
decades of experience as well as the ongoing development of the technology ensure
that customers' design and functionality requirements are met. 


Our customers can now select suitable surfaces from a wide range of patternsor develop
individual structures based on these patterns. Our steadily growing development department
will support your ideas – from the initial design through to the implementation. We can also
visualise new individually developed surfaces on prototypes on request to enable you to make
the optimum decision.. It is also possible to check the interaction between the structural image,
structure depth and gloss level through the production of initial or master patterns (virtually all
common plastics are possible).

Etching technology - the "hard facts"

  • A purely manual process with a minimal degree of automation
  • Material removal by means of a chemical reaction (acids)
  • Areas not to be etched are accurately covered
  • Multi-layer etchings are feasible
  • Heavily dependent on the material (steel) used and the mould contour
  • Structural limits in the tool must be precisely defined
  • Requires polish grades of at least 320
  • Production-related tolerances of up to +/- 10 µm are required
  • ...and many more
