Working principle and application range of ultraviolet laser marking machine

In the field of modern precision processing, the traditional laser marking machine uses laser heat treatment technology, and its fineness is limited. In this context, the UV laser marking machine has become the darling of the new era. It uses a cold working process called “illumination” effect, that is, “cold working” (ultraviolet) photons with very high load energy, which can destroy the chemical bonds in the material or surrounding medium, so that the material does not heat up. Therefore, the fineness and thermal effect are minimized, which is a big leap in laser technology.
Working principle of ultraviolet laser marking machine:
The reaction mechanism in UV laser processing is realized by photochemical ablation. Therefore, that is to say, the laser energy is used to destroy the bonds between atoms or molecules, so that it can become a small molecule and evaporate. The focus is very small, and the processing heat affected zone is very small. Therefore, hyperfine marking and special material marking can be performed.
Scope of application:
Nowadays, with the rapid development of laser equipment and the improvement of UV laser marking machine power. However, the UV laser marking machine is used in the high-end market of ultra fine processing, and is used on the surface of packaging bottles for iPhone, cosmetics, drugs, food and other polymer materials. Marking; Flexible PCB marking, micro hole cutting and blind hole processing; LCD liquid crystal glass, glassware surface, metal surface electroplating, plastic buttons, electronic components, gifts, communication equipment, building materials and other fields.
