The connection and difference between 355nm ultraviolet lasers and green laser marking machine

Talking about the connection between the ultraviolet laser marking machine and the green laser marking machine, both of them are actually marking machine equipment, but the materials and effects are different, and the principles and configurations used are also different. The effect is the same to achieve the effect of marking processing.

The output wavelength of the UV laser marking machine is 355nm, which can achieve better contrast marking results on many plastics that other lasers cannot mark, such as medical catheters and highly corrosion-resistant 17-X stainless steel materials. Compared to fiber lasers, Nd:YVO4 lasers and even green lasers, UV lasers can achieve better marking quality on almost all materials. The 355nm wavelength further increases the range of plastic materials that can be marked, in addition to the ability to strictly control heat input when marking on metal materials.

Ultraviolet laser marking machine is a product in the series of laser marking machines, and it is also a newly developed laser processing technology. Because the laser used in traditional laser marking machines is thermal processing technology, the fineness has been improved. The development of space is limited, but the UV laser marking machine adopts a kind of cold processing, so the fineness and thermal influence are reduced to a very low level, which is a big leap in laser technology.

The green laser marking machine is suitable for some plastics, silicon and reflective metals. The green light output by the laser is at a wavelength of 532nm, which can achieve a good contrast mark, can achieve soft marking on silicon materials of plastic materials, and can also achieve high-quality gold and silver reflective marking materials.

And when laser engraving, there is no need to worry that the incoming laser will melt the material in a straight line, because the laser maintains the form of light energy when passing through a transparent object, and will not generate excess heat, only at the interference point will it be converted into Internal energy and melts matter.

The green laser marking machine is very suitable for the marking of glass products, marking on eggs, mobile phone screens, LCD screens, optical devices (such as optical lenses), automotive glass, etc. In addition, it is also suitable for the processing of most metal and non-metal materials, such as electrical appliances, communications, electronic components, electrical products, integrated circuits, hardware tool products, auto parts, plastic products, craft decorations and other fields. Compared with similar products, the green laser marking machine has quite high cost performance and is very popular in the market.
