What Does a Laser Marking Machine Do? A Complete Guide
.jpg)
The Blog A laser marking machine is a precision device widely used across industries to create permanent markings on various surfaces. Utilizing a focused laser beam, it produces highly accurate and durable marks. Unlike traditional labeling methods, laser marking requires no consumables and minimal maintenance, making it a cost-effective solution. Laser marking machines work by directing a concentrated laser beam onto the surface of the material, generating heat and altering its properties. The process depends on components like the pump source, lasing medium (e.g., CO2, organic dyes), and optical resonators. Popular techniques include laser etching , which melts the surface for barcodes or logos; laser engraving , which creates depressions by vaporizing material; and laser annealing , which changes surface colors for industries like automotive and aerospace. The types of laser markers include CO2 laser marking machines , UV lasers , and fiber laser machines , each tailore...
