What are the classifications of laser marking machines

Laser marking machines are often called laser engraving machines, laser marking machines, and laser coding machines. Many end users call them laser machines. In the laser industry, practitioners are more specific in their descriptions and classifications, and can recommend suitable models based on actual conditions after customers have stated their requirements.

Laser marking machines can be classified according to the core principles of working materials or work purposes. Jinbofang laser finishing related materials introduces the types and functions of several common marking machines in the current market.

Laser marking machines have been very mature after decades of development. From gold-plated cavity marking machines to picosecond marking machines, they have witnessed the development of the laser marking industry. At present, the mainstream marking machines on the market are divided into fiber laser marking machines. , CO2 laser marking machine, ultraviolet laser marking machine, semiconductor laser marking machine, flying laser marking machine.

1. Fiber laser marking machine:

Mainly used in: plastic, electronics, metal, ceramics, tobacco and other materials to mark the required text, pattern, bar code and other graphics. The fiber laser marking machine is easy to operate and has the advantages of fast and clear marking, which makes the company The production efficiency is more efficient. Our commonly used pulse lasers are 10W, 20W, 30W, 50W.

2. Ultraviolet laser marking machine:

The applied industry is the same as the fiber laser marking machine, but the printed text and patterns will be more precise and clear. It is mainly used for the main products that enterprises have higher requirements for text and patterns, especially some fiber laser marking. When the machine is unable to mark the desired effect, the extreme strength of the UV laser marking machine is reflected, because the UV laser marking machine belongs to the cold light category, and many products fiber laser marking machine cannot mark the satisfactory effect UV laser Marking machines can generally mark out. Commonly used UV lasers on the market are 3W, 5W, 7W, 8W, 10W, 15W.

3. Carbon dioxide laser marking machine:

The CO2 laser marking machine uses a laser beam to make permanent marks on the surface of various materials. The effect of marking is to expose deep material through the evaporation of surface material, thereby engraving exquisite patterns, trademarks, dates, LOGO or text. At present, CO2 laser marking machines are mainly used in some occasions that require finer and higher precision. Used in food, medicine, wine, electronic components, integrated circuits (IC), electrical appliances, mobile communications, building materials, PVC pipes and other industries, the main advantage of CO2 laser marking machines and inkjet printers is that they have no consumables and are permanent.

4. End pump laser marking machine:

The main application industry is also the same as the fiber laser marking machine, and its performance is similar to that of the fiber laser marking machine, but its peak power is higher.

5. Green laser marking machine:

Mainly used in the surface and internal marking of glass and crystal products, ceramics, metals, electronics, plastics and other products. It belongs to the category of cold light, and it is also very suitable for some products that have a larger response to heat and require higher precision.

6. Semiconductor laser marking machine:

The working principle of semiconductor laser pumped solid-state lasers (DPSSL) for laser marking is to use high-power semiconductor quantum well lasers instead of gas lamps to pump solid crystals as gain medium laser resonators to generate lasers of new wavelengths. Crystals are being used The backup frequency mixing should produce SHG, THG and other wavelength lasers. Through the design, the entire laser marking process, operating procedures and quality standards from re-inspection of raw materials, production, process inspection, final assembly commissioning to final product inspection have been established.

7. Flying laser marking machine:

It is a dynamic marking function developed on the basis of the above several laser marking machines. It is mainly used in assembly line operations. It can mark products without restrictions for 360 days. It can also automatically generate serial numbers and batch numbers, which greatly improves the company. The production efficiency can also save a lot of labor.

There are many types of laser marking machines. At present, there are many 3D laser marking machines for surface marking, large-scale immovable handheld laser marking machines, etc., and these two types are based on the type of work. For classification, in summary, it is divided into fiber, CO2 and UV laser marking machines according to the working material of the laser.
