Fiber Laser Marking Machine, generally speaking, it is a kind of laser marking machine using the fiber laser, to mark on different kinds of materials permanently. There are principles to make the marks or signs on the surface of the material. The first principle is to evaporate the surface layer substance and shows the deeper layer substance. The second is to make the surface has a mark or sign through laser light energy that leads to a chemical-physical change of the material. The third principle is to burn the part of the substance by the laser beam and then shows the needed engraved marks and shapes.
The fiber laser marking machine mainly consists of laser, lens, marking card these three parts. Fiber laser marking machine has excellent fiber laser beam quality, the output wavelength is 1064 nm, the shelf life can last 100,000 hours, is much longer than other kinds of laser marker. Its electro-optic conversion efficiency is above 28%, compared to other kinds of laser marking machine’s conversion efficiency 2%~10%, fiber laser marking machine has the absolute advantage, This also makes it have excellent performance in energy saving and environmental protection field.
The fiber laser can be divided into two main categories: one is a continuous fiber laser, another is pulse fiber laser. And their power range has large differences.
- power of continuous fiber laser: 5 watts, 10 watts, 20 watts to 400 watts, largest can be 4,000 watts.
- power of pulse fiber laser: 10 watts, 15 watts, 20 watts, 25 watts 30 watts or 50 watts.
Fiber Laser Marking Machine is widely used in mobile button, plastic transparent button, electronic parts, IC, tools, communication products, bathing products, tool accessories, glasses and watches, jewelry, button decoration for boxes and bags, cookers, stainless steel industry and so on.
