Laser engraving and laser marking

 

A wide range of materials can be quickly, reproducibly engraved or marked by lasers, with high quality, as single or series parts. Suitable materials include all metals and alloys, very many types of plastic, and ceramics and graphite electrodes.

In tool and mold manufacturing, laser engraving is an alternative to die sinking or milling. This is especially true when intricate contours have to be applied to the component surface in one pass. 3D laser engraving is also used for producing erosion electrodes with very fine structures and geometries.

Perforation and cutting of rubber mold parts from natural rubber and similar materials are another application for the laser engraving system.

Lasergravur und -beschriftung

To complete your individual engraving orders, we need the material data, such as CAD data, as described below.

2D engraving and marking:

  • 2D CAD data as *.dxf or *.dwg (AutoCAD R14 format)
  • 1:1 scale
  • Script, symbols and logos as contours
  • Intact, closed contours
  • Standard texts also as text block in correct font, size and position
  • If fonts are not standard in Microsoft Windows, please include them with delivery
  • Engraving depth data

Qualitätskontrolle nach der Lasergravur

3D engraving:

• 3D data, preferably as ProEngineer *.prt file. We work with ProE Wildfire 4.
• Naturally also compatible formats for data exchange (such as *.stp or *.igs)
• We require the part to be processed as a “clean”, complete, intact solid with “real engraving” (no surface or wire-frame models, no assemblies).
• The volume to be removed (engraving) is also required as a solid, as described above. This must be within the same coordinate system as the aforementioned part.
• To reduce the amount of data, please leave out irrelevant details, such as cooling holes.
For 2D engravings, you can also provide us with 3D data.

Direct communication with your designer is a good idea for determining the necessary engraving data.
Marking and engraving on unusual materials are done on samples ahead of time and submitted to the customer for approval.

We look forward to your query.
