What is Laser Etching & Engraving?

Laser etching and engraving refer to a permanent mark that is made when a laser removes material from the surface of an object. This marking can be done on almost any part, making it a great solution for traceability in a variety of industries.


What is the difference between Laser Etching and Laser Engraving?

Both laser etching and engraving are types of laser marking. The main difference between the two techniques is depth. As the depth of the laser etched mark increases, it is often referred to as engraving. The mark left by laser engravers and laser etching is permanent, weather-resistant, and great for a variety of applications.

Materials and applications best suited for laser etching & engraving:

  • Metals: Steel, aluminum, brass, etc.
  • Wood
  • Ceramics
  • Glass
  • Polymers

Laser Engraving is used in a variety of industrial applications

  • Etch barcodes and serialized part identification onto mirrors
  • Engrave barcodes into various components and sub-assemblies
  • Etch barcodes onto wheels for traceability and NHTSA compliance 
  • Laser etch logos and icons on various plastic components and buttons
  • Engrave VIN numbers
  • Surface etching product information on circuit boards, plastic housings, and semi-conductor parts
  • Replace labels for permanent traceability
  • Laser etch small barcodes to help protect against counterfeiting
