Laser Etching & Engraving Applications and Machines

What is Laser Etching & Engraving?

Both laser etching and engraving fall under the general category of laser marking. Laser etching and engraving are similar in that they produce permanent marks created when a laser removes material from the surface of an object. 

These versatile part marking methods can be used on almost any material, making them an ideal solution for a variety of industries that require permanent marks for part identification and traceability. There is also a range of industrial applications where manufacturers can use laser etching and engraving to mark the following:

  • Text
  • Logos
  • Date or time stamps
  • Serial numbers
  • Barcodes
  • 2D Data Matrix codes
  • Other important manufacturing information

What is the Difference between Laser Etching and Laser Engraving?

The terms laser etching and laser engraving are often used interchangeably, but there are some important distinctions between them.

The key difference between these techniques is the depth of the mark. As the depth of the laser etched mark increases, it is often considered engraving followed by deep engraving

The method you select is dependent on the type of mark you want to achieve. For instance, some post-processing applications such as galvanizing require greater mark depth to ensure mark quality and readability. Certain industries also require particular marking depths to meet regulatory standards.

Laser Engraving 0.0001 - 0.005 in. Depth
Deep Laser Engraving > 0.005 in. Depth


How do Laser Etching and Engraving Work?

  • To create permanent marks, laser etching and engraving processes start with a beam of concentrated light energy.

  • The laser beam targets a small area of the material, known as the focal point.

  • The heat generated by the light energy allows the laser machine to alter the material's surface, while the focal point ensures it affects only a specified part of the surface.

  • The result is a smooth, high-contrast, lasting mark, which can be human readable (serial number) or machine readable (barcode), etched or engraved into the part's surface. 

In the laser etching process, this mark will reach a depth of about 0.0001 inches. In the laser engraving process, the mark depth is typically up to 0.005 inches.

A subset of this process, known as deep laser engraving, is characterized by a mark that is greater than 0.005 inches deep. These marks are extremely durable and beneficial for industries where marks need to withstand harsh conditions.


What Types of Laser Engraver Technology will Make These Marks?

Beyond the marking process, another critical factor in getting the final mark you need is the laser engraving technology. While many variables affect your choice in laser engraving machine, there are a few common technologies used for laser etching and engraving:

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
