UV Laser Marking Machine

UV laser marking machine use the wavelength of 355nm ultraviolet laser, which has very small focus spot and can greatly reduce the mechanical deformation and processing heat effect of the material.UV laser is mainly used for ultra-fine marking, especially suitable for food, pharmaceutical, micropores punching, high-speed cutting of glass materials and the complex graphic cutting of silicon wafers.

UV laser marking is a kind of cold laser technology. The High-energy molecules of ultraviolet photons can directly separate molecules from metal or non-metallic materials which need to be processed, then this separation causes the molecules to be separated from the material so that the way they work does not produce any heat. This is very different from traditional fiber and carbon dioxide laser marking machines.

Differences from other laser marking machine

1. The wavelength of UV laser is only 355 nm, while fiber is 1064 nm and CO2 is 10.64 μm. When the wavelength is shorter, the laser bean is smaller and more precise, and the Heat-affected zone formed during processing is smaller also, which makes the marking accurate and fine.

2. CO2 laser marking machine and fiber laser marking machine are physical marking method, but UV laser marking machine is a chemical processing method, mainly by photochemical reaction. The difference is that the physical processing method is mainly happed on the surface of the material, while by chemical processing method, the laser can proceed deep inside of the material.

3. Fiber laser marking machine is mainly used in metal material. Due to the heat generated by its beam, it is not suitable for marking high-precision special materials. UV laser marking machine is particularly suitable for high-end market which need ultra-fine processing, such as marking of cosmetics, pharmaceuticals and other packages by polymers materials.
