The laser beam only removes the anodized layer from the aluminum piece resulting in high quality marks.

Yag for yttrium aluminum garnet is a crystalline solid state laser that emits a wavelength of 1 064 micrometers 1064 nanometers. This type of laser is capable of scribing right through the anodic coating to the bare substrate underneath. One piece of equipment they have i. Barcodes data matrix codes dmc alphanumeric numbers can be engraved directly on the surface.

There are two types of lasers used for etching or scribing laser engraving metal surfaces. Laser marking engraving or etching of anodized aluminum is perfect to do direct part marking. Anodised aluminium can be engraved efficiently and precisely with a laser machine. See all the benefits associated with the use of an automated or manually loaded laser marker.

While this method is perfectly suited for coloured anodised coatings for natural anodised. Another important point when engraving anodized aluminium is that the engraving must be done fast.
