What Is Asset Marking & Why You Should Start Doing It

There are a number of differing changes to the material surface during the laser marking of plastic, and it is very dependent on the material itself as to which one occurs.

  1. A thermochemical foaming, creating gas bubbles to the surface of the material, is the most common. The light scatters across the affected area, producing the light marking that appears.
  2. Bleaching is another effect that is common. Here the pigment used to achieve the product colour is removed creating a visual difference.
  3. The third mechanism is vaporisation, where the material is heated very quickly, to the point where it vaporises and is removed leaving behind the created image.

These three laser marking effects can be enhanced, by the adding of laser sensitive additives, and can generate considerable advantages. The additive acts as an abortion barrier, boosting the ability of the laser to process better. In some materials, the laser machines ability to mark the product would not be possible without this additive.

In this case, the plastic reacts very well to the YAG wavelength, creating a contrast to the surface. The die within the plastic is removed (bleaching), providing a mark that is permanent.

Laser Marking Anodised Aluminium

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. As like with our customer HGL Dynamics

Product Branding By Laser Marking Anodised Aluminium

Product branding by laser marking anodised Aluminium

A good example of product branding by laser marking anodised aluminium is customer Dynamic Audio. 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…
