Basic Principles Of Laser Marking Technology
Before understanding how laser marking technology integrates with other manufacturing processes, you need to understand the basic principles of laser marking technology. Laser marking technology uses laser beams to process the surface of workpieces. Its basic principles mainly include the following aspects:
- Laser emission: The laser marking system emits a high-energy, high-consistency laser beam through a laser generator. Commonly used laser generators include carbon dioxide laser generators, fiber laser generators, and semiconductor laser generators.
- Laser focusing: The laser beam is focused into a small diameter spot through optical elements such as lenses or mirrors, so that the laser energy is concentrated into a small area, thereby improving the accuracy and efficiency of processing.
- Material absorption: After the laser beam irradiates the surface of the workpiece, the light energy is absorbed by the material, causing the temperature of the local area to increase. Different materials have different absorption rates of laser, so the optical properties of the material need to be considered during the laser marking process.
- Mark formation: The high-energy laser beam causes chemical or physical changes in the surface material of the workpiece to form marks. This change may be surface oxidation, evaporation, or a change in the material structure, thereby forming clear logos, patterns, or text on the surface of the workpiece.
- Control system: The laser marking system is equipped with a sophisticated control system, which can control the movement path and power of the laser beam according to pre-designed patterns or text to achieve precise control of the processing process.
