UV Laser Marking Machine

Due to different principles, the laser marking machine distinguishes many models and labels. UV laser marking machines are an important part of this.

1. Working principle

UV laser marking machine belongs to the series of laser marking machine, but it is developed by 355nm UV laser. The machine uses three-stage intracavity frequency doubling technology to compare with infrared laser. 355 UV focusing spot is very small, can be The mechanical deformation of the material is largely reduced and the heat of processing is small.

UV laser marking is cold processing, UV laser processing is called "lighting" effect, "cold processing" has high load energy photons, which can break the chemical bonds in materials (especially organic materials) or surrounding media. To cause the material to undergo a non-thermal process damage. There is no effect of heating or thermal deformation on the inner layer and the surrounding area of the surface to be processed.

2. UV laser marking machine advantages:

⑴ Laser beam quality is good, it can achieve ultra-fine marking;

⑵ The heat affected area is very small, the processing material is wide, and the cost performance is high;

⑶The machine performance is stable, small size, low power consumption, long-term operation;

⑷ Good design for installing and operating;

3. Application range

 It is mainly used in the high-end market of ultra-fine processing. The surface of packaging bottles for pharmaceuticals, cosmetics, foods and other polymer materials is marked with a very fine marking, which is clear and firm, superior to ink coding and non-polluting.

⑵ Flexible PCB board marking, dicing, silicon wafer micro-hole, blind hole processing.

 LCD liquid crystal glass two-dimensional code marking, glass surface punching, metal surface plating marking, plastic buttons, electronic components, gifts, communication equipment, building materials and so on.
