How a Laser Marking Machine Works

• Laser marking is based on the interaction between a laser beam and the surface of a material. When the focused beam hits the surface, it causes localized heating, oxidation, carbonization, or micro-engraving. These changes create a lasting mark that cannot be easily erased or worn away.

1. The system uses a galvanometer scanner to rapidly direct the laser beam, allowing it to trace characters, graphics, and codes with exceptional accuracy. High-speed marking ensures efficiency even in mass-production environments. Because laser marking does not use ink, solvents, or contact-based tools, it is cleaner and more consistent than traditional printing or mechanical engraving.
