Material Glass with paint finish

A request from the bride-to-be, to create a wedding day \favour\ for her guests. The glass bauble is coated on the inside with various painted coatings providing the finished colour, in this case a white base colour. Nd:Yag Pulsed laser marking, at a very low frequency and power setting, was used to create the effect. The laser wavelength passes through the glass leaving it untouched but removes the paint or ink on the inside, to leave a perfect image of the  happy couples’ day. There was only one potential issue to look out for, if the bauble is too small, then the laser beam may still be close enough to focus to mark the opposite site as it exits the component. The laser marking process at this wavelength does not damage the glass as it passes through.

If you wish to replicate this process the baubles must be glass. If plastic is used, it is likely that the plastic will absorb the energy at the surface and damage the part.

It is also possible to use Thermark surface additive on glass. Althouth difficult to set up and get parameters spot on, it is achievable.

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 between 10 and 25 microns, generally between 10 and…

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,…
