From medical to technical, lasers are everywhere. You might have learned of laser treatments, but have you learned about laser marking? Okay…to make it simple for you, think of wood carvings. Now imagine the same on metal. Well, it is not exactly like that but yeah it somehow resembles. Let’s discuss the laser marking system in detail in the current blog post.
Laser Marking System
Which is your favorite car? Do you Mercedes? How about the logo? Have you ever brainstormed how it was prepared or if it can be prepared? The answer is “Laser marking”. As the laser gives you a concept of a “beam of lights”, marking it means “leaving an impression”. So, collectively, using beams of lights, you create an impression on a surface. Let it be a logo or any design. The types of lasers usually used are;
- Fiber Lasers
- CO2 Lasers
- Pulsed Lasers
- Continuous Lasers
While there are 3 common uses of laser marking;
- Laser annealing: It is the practice of creating an impression or mark beneath the metal surface keeping the base or protective covering intact.
- Laser etching: It works at high speed and high efficiency creating a high-contrast permanent impression or mark on the surface.
- Laser engraving: It is a common practice that involves creating deep and permanent marks that resist scrapes.
By using the laser marking technique, you can mark the following materials;
- Stainless steel
The automobile industry heavily uses laser marking techniques to distinguish its products with 2D barcodes, serial numbers, and logos.
Laser Marking: How does it work?
The laser marking technique involves using intense beams of light to leave a permanent mark on the surface. When you focus the beam on the surface, upon hitting, the energy is transferred in heat form, giving black, white, and in some cases, colored marks.
LASER phenomenon is behind the laser beams generation. Photons are released on energized stimulation of a special pattern. Now, these photons stimulate the material again and generate more photons. It will lead to photons accumulation in the laser cavity. Now, this accumulated energy is cast as a single, coherent beam of light using a mirror on the target. Depending on the energy level, laser marking is used for etching, engraving, or annealing surfaces with high precision.
Manufacturers are fond of using laser marking technology for different purposes. There are endless applications of laser marking technology in comparison to old traditional methods such as inkjet printing, etc. Visit lasitlaser.de for more details about laser marking.
