How Many Types of Laser Marking Machines?

If you want to buy a great CNC laser marker for sale. Then, the first thing you need to know is what kinds of laser marker machines are in the market. And among those colorful laser marking machines, which one should I choose? Here I will make a brief introduction of the laser marking machine type to give you an answer.

According to different judgment standards, laser marking machines can be divided into a lot of types. For example, the CNC laser marking machines can be classified according to laser wavelength, laser generator, laser visibility, and laser source.

According to the laser wavelength, it can be divided into 532nm laser marking machine, 808nm laser marking machine, 1064nm laser marking machine, 10.64um laser marking machine, and 266nm laser marking machine. While depending on the laser generator, it can be classified as a CO2 laser marking machine, semiconductor laser marking machine, YAG laser marking machine, and fiber laser marking machine. And in the light of the difference in laser visibility, it has types of UV laser marking machines, green laser marking machines, and infrared laser marking machines. But the most common classification is based on the laser source- fiber laser marker, UV laser marker, and CO2 laser marker.

At present, the most widely used model is to use fiber laser to realize the marking function through an ultra-high-speed scanning galvanometer system. Fiber laser marking has high electro-optical conversion efficiency. It adopts the air cooling method and has the features of small size, good output beam quality, high reliability, long operating life, and energy saving. And it can also engrave metal materials and some non-metal materials. it is mainly used in fields with high requirements on depth, finish and fineness, such as mobile phone stainless steel accessories, clocks, molds, IC, mobile phone buttons, etc. Bitmap marking can mark beautiful patterns on metal and plastic surfaces. And the bitmap marking speed is 3-12 times faster than traditional first-generation lamp-pump marking machines and second-generation semiconductor marking machines.

The ultraviolet laser marking machine is also known as a UV laser marker. It belongs to cold light or ultraviolet laser marking. Generally speaking, a UV laser marking machine can realize finer and clearer marking. And it is mainly used for products that have higher requirements for text and patterns. The commonly used UV lasers on the market are 3W, 5W, 7W, 8W, 10W, and 15W.

The CNC CO2 laser marker uses CO2 gas as the working substance. It adopts the CO2 metal laser, beam expander focusing optical system and high-speed galvanometer scanner, with stable performance, long service life and maintenance-free. The CO2 laser is a gas laser with a laser wavelength of 10.64m, which belongs to the mid-infrared band. CO2 lasers have high power and electro-optical conversion rate.

Read this article, you may have a general understanding of the laser marking machine types. And we will always be online in time to give you the best laser marking solution. Looking forward to your contact.
