Laser Marking Services Near Finchley on Anodised Aluminium – Olive Audio Visual Ltd
In this case study we visit our customer Olive Audio Visual Ltd . For this customer we did laser marking of anodised aluminium. In this case the laser marking of audio and visual equipment. Our role was to provide product branding and relevant contact information for the customer.
For the Laser marking of anodised aluminium for this customer, was done on our inhouse flash lamp Nd:YAG laser system with a f-180 F-theta lens. In this example, the images being laser marked are quite large, the panels are processed using high power to start. Then we finish off using a second pass, with lower power effectively skimming the image.
CO2 lasers can also be used to process anodised aluminium. In this case, it is the dye that is directly affected rather than the material. The energy from the laser creates a heating action that removes the dye from the surface. The use of CO2 is generally not as well received as Nd:YAG Laser or Fibre laser due to the lower quality created by the mark process. This is directly related to the fact that the heating effect is difficult to control, due to “heat creep”. Although, per unit cost will be slightly higher with CO2 due to the process time being slower.
The benefit of CO2 laser marking anodised aluminium, is that the anodised surface is not damaged in any way by the CO2 laser source. This means there is no compromise in the integrity of the surface and no potential corrosion point. In applications such as aerospace and marine, where corrosion is a major risk, CO2 laser marking is usually preferred.
For these components being laser marked, a standard jigg was used to locate and hold the components in place and in the correct orientation. These marks are repeatable to a greater accuracy than 0.1mm.
These components are used in a mainly the entertainment industry, being incorporated into home entertainment systems around the UK. For more indepth information and to view all other offering at the customer please visit Services | Olive
