The laser wavelength of the UV laser marking machine is 355nm, the laser is a cold light source (so it is often called cold light laser marking machine), the focus spot is very small, and the processing heat-affected zone is very small, and the heat effect is particularly small during laser cutting or marking , It is more suitable for deep processing of materials that are more sensitive to thermal influence, so it can be used for ultra-fine marking, engraving, and thin slice cutting.

Ultraviolet laser marking machine is suitable for a wide range of materials, which solves the problems of insufficient marking and poor effect of many materials with fiber optics, green light, carbon dioxide and MOPA machines.

UV laser marking machine is mainly used in the high-end market of ultra-fine processing: marking of polymer materials and brittle materials; removal of metal or non-metal coatings; scribing of various materials and blind groove processing; new ultra-thin metal foil micro-holes Production; marking and scribing of flexible pcb boards; processing of micro-holes and blind holes of silicon wafers; drilling of glassware, etc.

Below, Foshan Fulan Laser briefly talks about the advantages of UV laser marking machine in the field of precision processing:

1. Super fine marking

The UV laser marking machine produced by Foshan Fulan Laser adopts imported laser light source, with high beam quality and small focusing spot, which makes marking finer and higher definition; the smallest focusing spot diameter can reach 10um (micron), the smallest line width It is 0.01mm, and the marking is super fine.

2. Small heat affected area

High-energy ultraviolet light with a wavelength of 355nm directly breaks the chemical bonds of atoms or molecules on the surface of the material, and performs a "cold" treatment on the material. The heat-affected area is small, no heat effect is generated, and it can avoid the deformation or scorching of the processed material.

3. Fast marking speed

Galvo-type precision marking head, with fine marking effect and repeatable processing, the maximum linear speed can reach 12000mm/s.

The application of UV laser marking machine in the field of precision processing is also becoming more and more extensive. It provides fast and efficient solutions for fine processing, and plays an important role in the field of precision processing. The laser processing process is called the "photoetching" effect. The short-wavelength and high-energy photons are processed by "cold" to directly destroy the chemical bonds of the atomic components of the material without generating heat. The processed material has smooth edges and extremely low limits. Carbonization. Therefore, the UV laser marking machine is very suitable for the current fine processing. Excellent performance has been accepted by many industries and has become an important processing method in the field of precision processing.
