How Laser Engraving Works: A Step-by-Step Approach

1. Design Preparation: Design the desired image or text using a computer-aided design (CAD) software.
2. Laser Setup: Install the design into the laser engraving machine, align the work area, and adjust laser settings based on the material and desired depth of engraving.
3. Laser Engraving: The laser focuses a high-powered beam onto the material, selectively removing or etching the surface layer to create the desired design.
4. Post-Processing: After engraving, remove any excess material, polish the surface, or apply additional treatments to enhance the design.
