Useful information

The etching process allows fine structures to be created by removing material in thin sheets or metal foils without the application of external force. The spray etching process is an effective alternative to punching and laser technology. Today, it is used in circuit board manufacturing and has also become prevalent in the production of flat moldings. A particular advantage of spray etching is the fast implementation of templates to real workpieces. Instead of costly and time-consuming cutting tools, spray etching makes use of relatively affordable photomasks that can be produced quickly. They are manufactured using modern photo-technical processes. Computer-aided film production using CAD/DTP creates pilot series or series with low to medium quantities in a very short space of time. The advantages of spray etching are wide-ranging.

The following are particularly significant:

  • Short timespan between design and part production
  • Manufacturability of complex structures
  • Low initial and tools costs
  • No feathering on the edges of the workpieces


Range of etching technology services

The following are suitable for etching technology:

  • Equipment parts
  • Ground plates
  • Shielding plates
  • Screens
  • Code disks
  • Measuring grids
  • SMD templates
  • Model components
  • Advertising media


At Union Klischee, we have been using spray etching as an industrial production process for more than 30 years. On request, we can also further process the etched components, e.g. bending, varnishing, printing and gold-plating. The following materials are suitable for etching:

  • Nickel silver
  • Stainless steel
  • Brass
  • Copper
  • Bronze


The above applies to sheets with a thickness of 0.03mm to 1mm.

Production tolerances vary depending on material and format, on average 0.05mm to 0.2mm. The standard format is 300 x 400mm. Other formats are available on request.

Technical details

The following materials are suitable for etching:

  • Nickel silver
  • Stainless steel
  • Brass
  • Copper
  • Bronze
  • Nickel
  • Constantan


Material thickness:
0.03mm to 1mm

Standard format:
300 x 400mm
Other formats are available on request.

Production tolerances:
Varies depending on material and format, on average 0.05mm to 0.2mm. We work in accordance with DIN ISO 2768 and/or DIN 16901.

To manufacture the etched parts, we require one of the following templates:

  • Film/film envelope
  • Camera-ready reflection copies
  • Sketch
  • Vector file (CorelDraw, PDF, EPS, AI, DXF)

We can also refine the finished etched items on request. You can choose from the following additional processes:

  • Bending
  • Varnishing
  • Printing
  • Laminating
  • Gold-plating
  • Nickel-plating

If the refinement process that you require is not listed here, simply call us or use our contact form to tell us what you need. We will be happy to advise you!
