Black Marking - Anodised
Aluminium Nametag

Step by Step Tutorial

Here, you can learn how to create black markings on anodised aluminium using a MOPA laser. A name badge is a great example for this kind of application. 


Preparation

You Will Need:

  • Anodised Aluminium
  • 1x Magnet

Machine Used:

You can use any machine from the SpeedMarker series. Or, you can use a Speedy fiber or Speedy flexx laser machine.

Important:

You may need to use different parameters to us if you are marking a glossy type of 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.


Step by Step

Step 1: Design

Firstly, import our template; or feel free to create your own. Import the PDF with layers into SpeedMark and assign the parameters and fillings to your object.

Important: If texts are imported from a PDF, they will need to be converted into curves beforehand. Otherwise, SpeedMark won't recognise them as 'text'. Alternatively, you can produce the text directly in SpeedMark to avoid the hassle of converting data.

Filling for: Fill Style: Line Distance: [mm]
Logo Cross Lines (Bidirectional) 0.03
Name Bidirectional 0.001
Title Bidirectional 0.001

Step 2: Laser Process

Now, you need to enter the parameter settings. Remember, these can differ depending on the laser machine used and its available laser power.

Laser Parameter Process Power [%] Speed [mm/s]
Logo Marking 50 2000
Name Marking 50 1500
Title Marking 50 1500
Laser Parameter Frequency [kHz] Pulse Width [ns] Passes
Logo 60 100 1
Name 200 8 1
Title 200 100 1

Step 3: Post Processing

Attach the magnet to the back of the finished nametag. It is now ready to use!


Inspiration

Try using different colours and sizes of anodised aluminium. This will add another element of quality to your nametags.
