What is the difference between several laser marking machines?

The alias of laser marking machine is laser marking machine, laser inkjet marking machine, laser symbol machine, laser engraving machine, laser marking machine, metal laser marking machine, fiber laser marking machine, semiconductor laser marking machine. So what is the difference between several laser marking machines? Let's take a look at the introduction of laser marking machine manufacturers.

One: CO2 laser marking machine. The current CO2 laser marking machine is usually the imported CO2 radio frequency laser tube, its service life can reach 20,000 to 20,000 hours, and the marking speed of this model can reach 7000mm/s. The CO2 laser marking machine is suitable for marking on most non-metallic materials, such as paper packaging, plastic products, leather fabrics, glass ceramics, etc.

Two: Semiconductor side pump laser marking machine. Semiconductor lasers use integrated module planning to replace the krypton lamp of the YAG laser marking machine, and then avoid the defect of frequently replacing the krypton lamp. The modular planning means that this model has fewer failures and protects It is also more convenient. The quality of the light model of the semiconductor laser marking machine is very good, and it is suitable for marking on various metals and non-metals, such as plastics, mobile phone keys, and stainless steel.

Three: Semiconductor end pump laser marking machine. Semiconductor end pump laser marking machine can be divided into three types according to laser wavelength, 1024nm infrared laser marking machine, 532 green laser marking machine, and ultraviolet laser marking machine. Currently, green laser marking machines and ultraviolet laser marking machines are popular in the market. The following is a brief introduction of these two laser marking machines.

1. Green laser marking machine: The green laser marking machine is suitable for marking materials that are sensitive to thermal effects, because the wavelength determines that the green laser is a relatively 'cold laser.' Relatively speaking, it means that the thermal radiation effect of green laser is smaller than that of co2 laser marking machine, semiconductor laser marking machine, and fiber laser marking machine. The typical application of green laser marking machine is to engrave and engrave the surface of crystal.

2. Ultraviolet laser marking machine: The ultraviolet laser marking machine is equipped with ultraviolet laser and imported high-speed scanning galvanometer system. Because the UV laser marking machine has a very small focus spot and the thermal effect of the UV laser is very small, the UV laser marking machine can perform ultra-precision marking and special material marking. The UV laser marking machine has a higher demand for marking. The customer chooses the product. Ultraviolet laser marking machine has the characteristics of high electro-optical conversion rate, stable operation of the whole machine, high marking accuracy, high working power, modular planning and easy device protection.

Four: Fiber laser marking machine. Fiber laser marking machine adopts imported laser, equipped with high-speed galvanometer scanning system (marking speed ≥8000mm/s) and professional laser marking software. As the price of fiber lasers continues to decrease, fiber laser marking machines will become the mainstream in the future. Because the fiber laser uses a modular design and integrated air-cooled device, the fiber laser marking machine is smaller than other laser marking machines.
