How Do Laser Marking Machines Work?
A laser marking machine uses a powerful light beam to mark an object with a certain material on a surface. It entails the precise directing of the laser beam in such a way that the surface color, surface features, or surface reflecting characteristics can all be changed. This is a result of localized heat energy causing a chemical change with melting of the surface or ablation of the material layers. Various laser marking types, such as engraving, etching, and annealing or discoloration, provide flexibility in terms of materials and applied methods. The mark that results is long-lasting, clear, and can be used industrially, commercially, and for beauty.
Understanding Laser Technology
The emission of lasers stems from stimulated radiation, which enhances light. By doing this, lasers form a beam of light rich in both energy and accuracy. Any of the following three components, energy source, an amplifying gain medium, or mirrors that converge the light into a fixed beam can be considered as a part of a laser. Due to the uniqueness of lasers in their characteristics, such as powerful collimation, coherence, monochromaticity, and directionality, they are extensively employed in telecommunication, industrial processes, medical procedures, and even scientific research.
Principles of Fiber Laser Marking
Fiber laser marking is greatly aided by fiber laser technology which engraves or marks differing materials with great precision and durability. This process employs a fiber laser, which serves as a power source and is known for its powerful output, stability, and prolonged lifetime. The basic concept is focusing a laser beam onto the surface of a material. The interaction of light with matte causes high energy to be concentrated, thereby leading to heating, oxidation, and alteration in surface texture. Such impressions are permanently engraved with a high degree of accuracy and can withstand harsh conditions.
Compared to other methods, fiber lasers mark some metals, plastic, and ceramics, as well as industrial surfaces, with high efficiency. Fiber lasers can reach up to 7000 mm/s with certain materials, which makes them consume less energy. The cavity of fiber lasers is usually filled with light at a wavelength of 1.06 micrometers. That primary wavelength can be absorbed by a large number of materials. Therefore, precise marking can be achieved with great control over thermal distortion. Even the most sensitive and complex components are guaranteed fine detailing as well as highly consistent, unrivaled results.
