Precise Laser Marking
Release time:2019-01-12

The laser marking technology is one of the largest applications in laser processing.

Laser marking is a marking method which locally illuminates a workpiece with a high-energy-density laser, causing the surface material a chemical reaction occurring like vaporization and color changing occurring and then leaving a permanent mark. Laser marking can mark a variety of text, symbols and patterns. The size of the characters can be from millimeters to micrometers, which has special significance on anti-counterfeiting.

The focused ultra-fine laser beam is like a tool. It can remove the surface material point by point. It is advanced that the marking process is non-contact processing without mechanical extrusion or mechanical stress. So it will not damage the processed object. As the size of the focused laser and heat-affected area the heat-affected area is small, and the processing is fine, the technologies which can not be achieved by conventional methods can be accomplished.
