MaterialAluminium, anodised black

Product branding anodised aluminium is a widely used application across many industrial sectors. The anodised process is removed to expose the aluminium base material using laser engraving.

The process

The finished image is created, when the laser removes material from the surface in a raster scan motion. This is followed by the laser beam being used to trace around the image outline, providing a sharper edge.

The quality of the finish on the aluminium is greatly dependent on the material quality. With poor quality materials (high levels of alloys), the grain structures have a tendency to tear leaving  rough surfaces and edges.

CO2 laser marking

Anodised Aluminium can also be processed using a CO2 lasers. With CO2 processing, the dye is removed without any surface disruption taking place. While this can provide certain advantages (corrosion protection), the quality of the mark is difficult to maintain. CO2 will heat the plate while attempting to remove the dye through a chemical reaction, and in doing so heat creep can occur. This shows up as blurred edges to the mark, and requires a very concise set up of the laser parameters.

Laser marking Anodised Aluminium – Electrical symbols

Anodising has become a dominant form of finishing for aluminium. This is largely due to its cost effectiveness, availability and suitability, across a whole host of applications and industrial sectors. Laser marking anodised aluminium, has also become an accepted process across these industrial sectors.

Anodising is an electrolytic passivation process. It changes the microscopic texture of the aluminium by modifying the crystal structure near the surface. The passivation thickness will be…

Product branding by laser marking anodised Aluminium

A good example of product branding by laser marking is anodised aluminium. It is used in high end audio accessories in the form of cable tidies.  The aluminium is highly polished, prior to anodising, in order to achieve the high gloss finish on the part.

The laser process, delivers small pulses of energy to the component surface. These pulses have enough energy to vaporise the surface of the aluminium where the anodised coating occurs. This exposes the base material, aluminium,…
