The Process of Laser Engraving Aluminum

Aluminum laser engraving is the process of permanently marking a metal surface with a high-powered laser. The initial step in the process is to create the desired artwork, logo, or text using special software that interacts with the laser engraver. After the design is approved, the aluminum piece is placed firmly on the engraving bed.
