What is Laser Engraving and How Does it Work?
Laser Engraving or Laser Etching is a method that uses a laser beam to manipulate the surface of an object. This occurs when the laser creates high heat that will vaporize the material exposing cavities that will form the final image. This process is fast because the material is removed with each thud of the laser.
Creating Precise, Intricate Designs
Laser engraving machines utilize focused laser beams to vaporize material, creating precise and intricate designs. Here’s how they work on various materials:
1. Wood:
- Applications: Engraving on wood is popular for creating custom furniture, decorative items, and personalized gifts.
- Process: The laser beam burns away the top layer of the wood, leaving a detailed design. Different settings can be used to achieve various depths and shades.
2. Metal:
- Applications: Metal engraving is used for industrial parts, jewelry, and custom nameplates.
- Process: The laser marks the metal surface, creating a permanent design. It can be used on various metals, including stainless steel, aluminum, and brass.
3. Glass:
- Applications: Laser engraving on glass is used for creating personalized glassware, awards, and decorative items.
- Process: The laser creates micro-fractures on the glass surface, resulting in a frosted design. This process requires precision to avoid cracking the glass.
4. Plastic:
- Applications: Plastic engraving is used for labeling electronic components, creating custom signs, and personalizing products.
- Process: The laser melts the plastic surface, creating a raised or recessed design. Different plastics may require specific settings to achieve optimal results.
