The application of laser marking machine is getting closer and closer to life, and the development of UV marking machine in recent years can be said to have been advancing by leaps and bounds. UV laser marking machine uses ultraviolet lasers to directly destroy the chemical bonds that connect the atomic components of the substance. This method called “cold” does not heat the periphery but directly separates the substance into atoms.
The people’s awareness of food and drug safety is also constantly improving. In recent years, the country’s safety supervision of food and drugs has also been continuously increasing. The paintable modification of the production date of the product has been criticized by the majority of people. Many foods and drugs are returned to the oven after the expiration date and the production date is changed before being sold on the market. The practice of small workshops also caused many big factories to suffer unjustified injustices. The application of UV laser marking machine in the food and drug industry makes it impossible to alter the production date of food and drugs. Not only makes food and medicine safer, but also makes manufacturers and consumers more trustworthy.
UV laser marking machine belongs to a series of laser marking machines, but it is developed by using a 355nm UV laser source. This machine adopts a third-order intracavity frequency doubling technology. Compared with infrared lasers, the 355 ultraviolet light has a very small focus spot and can It greatly reduces the mechanical deformation of the material and has little processing heat impact, because it is mainly used for ultra-fine marking and engraving, and is especially suitable for applications such as marking of food and medical packaging materials.
Advantages of UV marking machine:
1. UV laser marking machine is equipped with imported violet laser, which has excellent performance, uniform laser power density, fine spot, and stable output light power.
2. UV laser marking machine is suitable for a wide range of materials and can realize ultra-fine laser marking.
3. UV laser marking machine has a small heat-affected zone, avoiding damage from processed materials and high yield.
4. UV laser marking machine does not require consumables, and the use and maintenance costs are low.
5. It is permanent and indelible, and the marking content cannot be destroyed as long as the surface of the object is not severely damaged.
6. The non-contact marking is used, which will not damage the object itself.
BEC Laser UV laser marking machine adopts high-quality UV laser light source. Compared with ordinary laser marking machine, the focusing spot diameter of the ultraviolet end pump laser is smaller and the marking effect is finer; the laser with narrow pulse width and the processing material have a short action time , The thermal effect is small, and the marking effect is more beautiful. Because of this feature, the UV laser marking machine has advantages that other laser equipment can’t match in the fine marking, fine cutting, and micro processing of special materials.
