This laser marked threaded coupling, has undergone a process called \blackening\. It is used to add mild corrosion resistance, for appearance and to minimize light reflection. When laser marked, the resulting images can be quite unusual. With this component, the resulting laser marking appears to be gold in appearence.

The shape of the component lends itself to marking on the flat surface, but using a radial software too, so the mark details follows the diameter of the product, which is a standard feature on most laser marking systems today. Removing the blackening, provides the highest level on contrast to the mark.

The combined precision of the beam placement, along with our tooling design, means the part and mark are precisely aligned every time we set up a new batch of parts. Tooling design uses a cross slot and dowel locating system, while jigging is specifically designed to accommodate both simple and complex shapes as required. The operating software holds positional data, so the laser and tooling are aligned.

We used an Nd:YAG Q-switched laser, in our M Series marking unit, to process the parts. It is important to make sure appropriate parameters are made, to ensure vapourisation to the surface takes place, without burning the base material, which in this case is steel.

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.

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

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,…
