Laser marking in simple terms is a method that is used to mark something permanently on a piece of wood, fiberglass, leather, cloth, glass, plastics, etc. using a specific machine. Way back in the 20th century, a vibrating or rotating tool was used to engrave on the above said things. But, with advances in technological development, we now have the use of co2 and fiber laser technology that is both high-powered is used to engrave or mark. The tools used do not use any ink or doesn’t touch the surface of the non-metal, but specific machines are used to do the job perfectly. Though many claim these as laser engraving, still there is a vast difference between the two. Laser engraving engraves into the object, whereas laser marking just discolors the portion without cutting through the surface. These kinds of marking are used to make graphics, logos, characters, bar codes, all kinds of numbers, identification batches, and much more. You can find fiber laser marking machines here.
As there are no inks or solvents used, they are environmentally safe in nature. As these markings made by the laser machines are permanent, they are mostly sought out for marking bar codes and other forms of tracking that are subtle and delicate. Nowadays, people have started using these machines popularly for certifying diamonds too. The disadvantage of the device is that there is a slight effect on the objects nearby due to the high-energy that is used. But, the effect is very slight and unnoticeable at times.
There are different kinds of laser marking machines available in the market, and each one of them has a different working principle.
Fiber Laser Marking Machine
Fiber laser marking machines are the rage as of late. You can find new fiber markers for sale online and see videos to better understand their speed and marking quality. They simply permanently etch or mark almost any metal objects. You can also process dark acrylics. But, if you need to engrave or mark most organic materials you need a co2 laser engraving machine. A fiber marker typically is used in conjunction with a PC which handles the laser interface software. They are widely used for marking on metals like steel, aluminum, titanium, copper, etc. Most manufactured products today need traceability and no better solution than using a fiber marking or etching machinery.

CO2 Laser Marking Machine
These kinds of machines adopt CO2 into a discharge tube, which is used as a medium to make markings. These are used to make markings, especially on non-metals like plastics, optic fiber glasses, leather, cardboard, etc. There is a PC attached to these machines which act as a controller and controls the whole process like direction, speed, intensity, the spread of the laser beam, etc.
Lamp pumped YAG laser marking machine.
There is a krypton lamp attached which acts as an energy source in these kinds. The method used is non-contact like any other such machine. This kind of machines are used on food packaging, cosmetic products, signboards, advertisements, etc. They are also used on acrylic and ceramic products.
Diode End-Pump Laser Marking Machine.
These also use laser beams with an air-cooled system. The laser is sent through an air proof system with a vacuum. These are used on materials like PVC, nylon, stainless steel, rubber, epoxy resin, etc. They are used in the field of jewelry, cell phone, scribing, engraving on films, etc.
Whether you are going to start your outlet or you already have one, laser marking machines are going to be an advantageous addition which would churn out a handsome profit.
All About fiber laser marking machine and what it can do
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 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 often changed, so the maintenance charges are low over the life of the machine. Minimal operator intervention is required for these machines once they are up and running. On a side note be careful what company you go with.
“Many are lured by low prices towards buying a laser direct from China suppliers. Sadly many of these suppliers do not understand quality or even the functionality of their laser machines that well. Their only interest is to sell. Remember you get what you pay for especially when it comes to laser machinery.”
