Laser marking encompasses a wide variety of applications in manufacturing. Laser marking can be automated and processed at high speeds while leaving permanent traceability on all kinds of materials, including steel, titanium, aluminum, copper, ceramic, plastic, glass, wood, paper and cardboard.
In simplest terms, laser marking is a permanent process that leaves a lasting mark on a surface through a variety of methods. This marking can be done with a pulsed or continuous wave laser.
When the beam interacts with the material’s surface, it alters the material’s properties and appearance by using a beam that creates a high-contrast mark. The most common types of laser marking are annealing, carbon migration, discoloration, engraving, and etching.
For identification purposes, laser marking is ideal for adding bar codes, unique identification numbers, QR codes and logos.
