CO2 laser marking machine can also be called carbon dioxide laser marking machine. Like ordinary fiber laser marking machine, the reaction mechanism in CO2 laser marking machine processing is realized by photochemical melting. That is, using laser energy to sever the combination between atoms or molecules. The focal spot is very small, the processing heat affected zone is very small, and it can be marked with ultra-precision and special materials.
With the rapid development of laser equipment, the power of carbon dioxide laser marking machine has increased, and it has been used in advanced industries such as ultra-precision machining, iPhone, cosmetics, medicine, food and other polymer materials. Flexible PCB board marking, patch, silicon wafer micro-hole, blind hole processing, liquid crystal glass, glassware surface, metal surface coating, plastic buttons, electronic originals, gifts, communication equipment, building materials and other fields.
The CO2 laser processing process known as photo-effect cold processing has high load energy (CO2) photons that interfere with the chemical bonds of the data or the surrounding medium, causing damage to the data to attack specific heat processes. This cold processing has special significance in laser symbol processing. Since it is not thermal ablation, it does not produce thermal damage side effects, and is a refrigerant that severes chemical bonds, so it does not heat or thermally deform the inner layer and adjacent areas of the machined appearance. Machining data has lubricated edges and extreme carbonation.
In the environment of industrialized large-scale automatic production line, CO2 laser marking machine can become the darling of industrial processing manufacturers due to the advantages of light quality, peak value, pulse width, and reduced thermal influence during processing to meet the needs of industrialized mass production.
Compared with the heating processing of CO2 and fiber laser marking machines, the details are very limited, so the continuous development and research of CO2 laser marking machines can easily solve the difficulties. The CO2 laser marking machine adopts the cold working process, and cold working has many advantages. Cut the chemical bonds of the material or the surrounding medium, so that the material is not easily overheated, damaged or deformed, thus affecting the aesthetics of the product. Today's CO2 laser marking machines are often used for the appearance of packaging bottles of polymer materials such as iPhone, cosmetics, medicines, food, etc. marking, flexible PCB board marking, LCD glass, glass bowl appearance, plastic buttons, electronic originals, gifts, communication equipment, etc. Precision high-end market. In all commodities, we can see some degree of text, patterns, etc. These patterns or words are actually marked with CO2 lasers. Compared with the traditional marking machine, the marking effect of the CO2 laser marking machine is more delicate, environmentally friendly, more intelligent, and more in line with the automation requirements of modern industries.
