In this tutorial learn how to create black laser markings on anodised aluminium using a MOPA laser source.
- Anodised aluminium
You might need to use other parameters when laser marking glossy aluminium.
Creating a black marking is only possible with the MOPA laser. This is the only laser that colors anodized aluminum black through short pulsing. The conventional fiber lasers in the SpeedMarker Series, Speedy Flexx or Speedy Fiber Laser, can only create white marking.
Begin by importing our template or creating your own design. Import the PDF with layers into the SpeedMark laser software and assign laser parameters and fillings to the object.
Important: If text is imported from a PDF, they have to be converted into curves before importing. Otherwise the SpeedMark laser software does not recognise it as text. Alternatively the text directly can be produced in SpeedMark.
|Filling for||Fill style||Line distance [mm]|
|Logo||cross lines (bidirectional)||0.03|
Now enter the parameter settings. These will differ depending on your laser machine, chosen laser source and the laser power available.
|Laser parameter||Process||Power [%]||Speed [mm/s]|
|Laser parameter||Frequency [kHz]||Pulse width [ns]||Passes|
You can experiment using different colours of anodised aluminium and different sizes to expand your product offering.
