What is a Co2 Laser Marking Machine and How Does It Work?
How does a co2 laser marking machine function?
The marking of materials with CO2 lasers is dependent on the accuracy of the beams emitted. A co2 laser marking machine emits beams generated from a mixture of gases which include carbon dioxide gas. When excited electrically, gas molecules emit energy, allowing photons to be released to form a beam of light. This beam is transmitted to the surface of the material marked or engraved. With proper changes made to the intensity or wavelength of the laser, marking or engraving can be done on metals, plastics, and even organic materials.
What are the primary components of a laser marking machine?
Co2 laser marking machines have distinct defining features. The laser beam’s source, the laser tube, is integrated with the machine. The beam is guided over the surface of the material by the galvo system. Marking laser machines are equipped with control units enabling the operators to change parameters and settings for marking or engraving, thus fulfilling the desired outcome. Finally, the machine is equipped with a cooling system that prevents overheating, thereby aiding in maintaining efficiency and longevity.
What is the difference between laser engraving and laser marking?
While commonly confused as one and the same, laser marking and engraving differ in nuance. Laser marking is a process that changes the surface of a material to create a mark without removing any material. It is ideal for marking barcodes, logos, and serial numbers as laser marking creates high-contrast marks. In contrast, laser engraving works by removing material from the surface to create a design or text, which results in deeper, more prominent markings. Both methods are integral to the versatility of co2 laser marking systems.
