Anodized aluminum offers durability, colorfastness and resistance to rust, making it popular in the aerospace, automobile and electronics sectors. It is unique because of its anodizing process which makes it possible to create vibrant colors that can last for many years with different functional values as well as attractive appearances. Nevertheless, marking anodized aluminum is difficult due to the hardening of its surface that might be compromised by conventional techniques.

With its precision, productivity, and ability to engrave complex details onto anodized surfaces; laser marking is perceived as a more optimal solution. This way, it would be possible to maintain all the advantages of the material while at the same time ensuring that markers are resistant to environmental conditions.

How to Mark Anodized Aluminum with a Laser Marker?

Design Preparation: The first step involves creating or selecting the design to be engraved.

Setting Up the Machine: The laser engraver is prepared by setting the specific parameters needed for the job, such as speed, power, and focus. These settings can vary depending on the material being engraved and the desired outcome of the engraving (depth, darkness, etc.).

For example, To achieve a white mark on anodized aluminum using a Raycus 30W laser engraver, the following settings are optimized:

  • Model: Raycus 30W
  • Hatch: 1 (single pass)
  • Power%: 100 (maximum output)
  • Angle: 90 degrees (perpendicular hatch pattern)
  • Speed: 2000 mm/s (fast movement)
  • Freq: 55 kHz (pulse frequency)
  • Loop: 1 (one pass)
  • Line Space: 0.03 mm (fine line spacing)

These parameters ensure a precise, high-quality white mark on anodized aluminum by utilizing full power for a single, fast pass with fine line spacing and a specific hatch angle.

Engraving Process: Once the machine is set up and the material is properly placed, the engraving process begins.

Laser Interaction: When the laser beam hits the material’s surface, it removes or alters the surface layer, creating a mark.

Final Product: The end result is a permanent, precise marking that can include text, logos, or complex designs.

 

What are the Applications of Laser Marking on Anodized Aluminum?

Laser marking anodized aluminum, therefore, becomes a flexible and long-lasting solution for various industries. The laser etching anodized aluminum is permanent and very precise; thus, it is considered perfect when improving the security, aesthetic features, and functionalities of a product. Here are some key uses.
