Laser engraving and laser marking of anodized aluminium
- Laser engraving
Pictures and inscriptions that are accurate down to the last detail on anodized coatings
- The protective oxide layer is not pierced through
- High contrast values can be achieved
- Extremely fine contours and details can be realised > 600 dpi
- Output in greyscale for photo / picture representations
- High level of repeatability with consistent quality
- Only low laser power required
- Immediate sample or serial production from Design or CAD systems possible
- Cost efficiency: even small batch sizes or medium-scale serial production
- Freely selectable contour profiles: particularly suited for customizing products
- Contact-free: so materials do not need fixation
For laser engraving and marking, the laser systems QuickMark, M-800 and M-1200 are particularly suitable.

Material information
Anodized and coloured anodized aluminium are ideal for inscribing or marking with laser. In this process the very hard approx. 8 - 30 µm protective anodic coating is not completely removed. The image contrast is produced by means of the change of colour in the oxide coating and almost photographic qualities can be achieved with over 600 dpi and up to 250 different grey scales. Special lacquer coatings can also be used to apply durable high-contrast contours or pictures to metallic surfaces, for example. Typical fields of application include high-quality markings for type plates, barcodes, logos, serial numbers etc., although the advertising media sector is coming to rely increasingly on this technology as well.
