Why Should You Purchase a Fiber Laser Marking Machine?

What are Fiber Lasers?

Fiber lasers are solid state lasers that use optical fiber to deliver an amplified beam from the seed laser. The amplification is done using pump diodes. The fiber is doped with rare earths like neodymium to achieve amplification. The laser beam does not lose its power even if the optical fiber is bent or coiled. The final output is incredibly focused compared to gas lasers and the temperatures achieved by the beam are up to 100 times better than comparable CO2 lasers. By eliminating expensive cooling systems, fiber lasers are much more compact and simple in design compared to CO2 lasers . Typically fiber lasers use air cooling as compared to the water cooling systems found in gas lasers. They have a long working life and high reliability, along with superior output compared to gas lasers. The light source does not have to be changed often so the maintenance charges are low over the life of the machine. The beam is controlled by means of computer systems. Minimal operator intervention is required for these machines once they are up and running.

How Does Fiber Laser Marking Work?

The heat of the laser beam on the marking surface produces oxidation in the material in the beam path. This manifests as a color change in the material. Since fiber lasers produce very focused beams of light, the pattern produced in the process can be very distinctive compared to the surrounding material and can produces an embedded effect without removing any material. The change is happening at the microscopic level, so the structural strength of the marked surface is not affected. The marking is controlled by an automated system and required minimal human intervention. Laser marking also does not use any dyes or inks to achieve the marking, which leads to lower consumable costs over the lifetime of the product. The systems are also conducive for continuous operation in busy industrial environments. Laser marking is finding preference among consumer electronics manufacturers for the high quality of the output which is both fade free and smudge free over the life of the product. High-end products like smartphones have brought laser marking to ordinary homes all over the world.

What are the applications of Fiber Laser Marking Machine?

Fiber laser marking machine can be used to produce text, logos and two dimensional codes in the surface. Because of the high temperature achieved by the beam, the process is most suitable for metals and some non-metallic materials which can withstand high temperatures. Laser marking (www.uniquelaser.net/laser-marking-machine.html) can be used to imprint the company name and logo on the product to give it a recognizable look without spoiling the product or damaging it. The part number can also be marked using laser to enable easy identification and tracking in use. Marking also enhances security, so that the parts made by one company cannot be passed off by another easily. Bar codes and part numbers can be marked to make high value products easily traceable. Counterfeiting can also be reduced. The industries and sectors which use fiber lasers include consumer electronics, aerospace, manufacturing, metals and minerals, household vessels and many similar areas.

Types of Fiber Laser Marking Machines Available

Depending on the type of application and power of the laser, different types of fiber laser models can be used by customers. The desktop model is most suitable for small and compact work areas. The beam power output is 10 watt. It can be used in continuous operation and can be customized according to the application requirement. The marking can be done over an area of 100mmX100mm to a depth of ≤0.01mm at a speed close to 9000mm/sec. The marking can be done on metals like steel, brass and titanium and non-metallic materials like PVC and PP. Another desktop laser marking system that can used for a long working life of up to 100000 hours. It can be used in continuous mode and has a power output of 20 watt with efficient electricity consumption. The system is air-cooled and can support designs from a wide variety of formats. Some fiber marking model comes with a high power 30 watt beam output. Its working life is more than 100000 hours and it can be used for marking logos, text and graphic codes.
