A great example of deep laser engraving/marking for the automotive industry.

Back in 2008, we began working with a model maker called Synapse. Most of the initial work covered high end prototyping for manufacturers such as Aston and Bentley.
The item in the image forms part of the vehicle cockpit, and provides the concept guys with parts that could be touched, looked at and modified to suit. Deep laser engraving/marking lends itself to this application. The objective was to use a deep laser engraving technique, that allowed the model makers to infill, using various inks in order to replicate night/day button detail. In this instance probably in the region of 0.2-0.3 mm.

Deep Laser Engraving/Marking

With the depths of this design, the difficulty is removing the material, while ensuring that the top surface is not damaged in any way. Deep engraving aluminium raisures, can form around the edge of the mark, when too much power is used during the process to keep costs down. In this instance, the process was run at a lower power using multiple passes, thus ensuring that raisures are kept to a minimum (the raisure is a small burr that forms around the engraving where the energy pushes non vapourised materials up).

In this application, we used a flash lamp Nd:YAG laser where you can select the mode structure, in order to match the spot size and power density to the material and application. Today the same job could be facilitated by a pulsed fibre laser, probably in the 50-70 watt zone.
The operating software allows the creation of automatically setting multiple passes for parts of the job or all of it. This allows for the careful removal of materials without burning or heat distortion.

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…
