Laser Marking Processes and Applications

The term laser marking is often used to describe the general concept of using a laser to create a permanent identification mark on to a part or product. Identification marks can be a company logo, a manufacturing code, date code, serial number, 2D data matrix mark, 1D barcode, or any type of mark required for regulatory compliance.

Laser marking can be broken down into several different types of marking processes. Generally categorized by how a specific material interacts with the heat from a laser or how that material is altered.
