One of the fastest-growing applications of laser technology is in identification. In manufacturing, laser engraving and marking open up a range of possibilities that enables better efficiency, more security, and exciting new capabilities.

Laser Identification Options

Laser engraving allows us to place important identification elements on production parts. These might include:

  • Barcodes
  • Serial numbers
  • Time stamps
  • Data matrix codes
  • Logos or other branding marks
  • Instructions and safety warnings
  • Device identifiers

The Advantages of Laser-Enabled Identification

There are numerous options for manufacturers to mark inventory. Why are laser marking and laser engraving edging ahead of alternative options such as etching, painting, and labeling? Here are just a few reasons:

  • Eco-Friendly: Lasers don’t utilize any extra materials to leave a mark. Rather, their concentrated energy change the composition of the material itself to leave lasting marks. That means no environmentally harmful chemicals are involved, as they may be in painting or chemical etching.
  • Durable: It’s easy for sticker labels and painted marks to wear off over time. This is especially true of many heavy-usage parts that we make in our shop. Laser marking and engraving can’t be removed or altered because it’s incorporated into the part itself.
  • Maintains Integrity of the Product: Laser marking is especially useful when you don’t want to compromise the composition of your original product. Keep the exact specifications and shape of the part, while still identifying it with indelible marks.

Laser Marking Versus Laser Engraving

Laser marking and laser engraving are the two most common approaches to laser-enabled identification. Although they sound very similar, there’s a slight difference between the two options. Laser engraving works somewhat like a brand, vaporizing a small top layer of the material in a designated pattern to create a textured mark that you can feel with your fingers. Laser marking, on the other hand, is a noncontact process that changes the surface color of the object, much in the way that a plastic object may change color when it’s subjected to high heat. Laser marking can’t be washed off, and doesn’t leave a cavity in the surface of the material.

Etching is another common process that we’re often asked about. Etching is usually used to mark metal. However, it should be noted that etching isn’t related to lasers, but is rather a chemical process that utilizes acidic corrosion to leave a mark.

Applications of Laser Engraving and Marking

As mentioned above, the ease and reliability of laser engraving and marking opens up many options for streamlining your processes and ensuring better quality and security. Here are a few ways that our clients have used laser marking in their industry:

  • Quality control
  • Minimize counterfeiting
  • Branding
  • Tracking and tracing
