Laser Etching / Laser Ablation
WHAT IS LASER ETCHING?
Laser etching (also known as laser ablation) is a permanent form of engraving in which very little material is displaced by using a laser machine. Marking depth for a laser etching application can be as little as 0.0001 of an inch. Usually, the process removes a coating layer from the base material, such as an anodized layer from metal.
If the material and coating are different colors, laser etching will create a high-contrasting mark that can be very appealing and easy to see. Oftentimes, the laser itself is causing the reaction and creates a heat mark without disturbing the surface of the material. Additionally, laser etching is quite durable being able to withstand non-abrasive treatments, such as e-coating, powder coating, and heat treating.
What types of material can be laser etched?
Laser etching is best done on bare or plated metals, lacquer-coated material, and special layering films.
WHAT TYPE OF LASER SOURCES ARE USED FOR LASER ETCHING?
WHICH INDUSTRIES OR APPLICATIONS USE LASER ETCHING?
The high-contrast, minimum-depth marks of laser etching is commonly used for logos and tracking and serial numbers in many industries including automotive, aerospace, electronics, firearms, and packaging.
