The UV laser marking machine works by utilizing a high energy beam emitted by a tunable UV laser to create a tiny oxidation reaction on the marked area of an object's surface by scanning the area at a high frequency.
This oxidizing reaction is a chemical reaction that creates a tiny trace on the surface of the object by breaking down the material on its surface into gases and liquids.
Because the UV laser is extremely powerful, it can mark a wide range of materials with clarity and precision.
Applications of UV marking machines
At present, there are many materials that can be processed by UV laser marking machine, the more common such as glass, circuit boards PCB/FPC, ceramics, plastics, silicone, acrylic, some metal and other products.
UV laser marking machine in this line of benefits is that according to the different needs of customers to do the relevant program, beyond the laser program power can choose 3W/5w/10w and other lasers, can be realized in different materials marking LOGO trademark, text, two-dimensional code, patterns, serial numbers, running numbers, symbols, jumbled numbers and so on. Of course, in general, the selection of ultraviolet laser marking machine power are smaller, but this is more convenient, compared to other laser marking machine, ultraviolet laser marking machine is a cold process, the process is called "photo-etching" effect, "cold processing". The (ultraviolet) photons with high loading energy can interrupt the chemical bonds within the material or the surrounding medium, so that the material undergoes a non-thermal process, and the inner layer and the nearby area do not produce heating or thermal deformation, etc. The final processed material has a smooth edge and a very low carbonization, so the fineness and thermal effects are done in perfect condition.
Advantages of UV laser marking machine
- High precision: the marking precision of UV laser marking machine can reach micron level, which can meet the demand of high precision marking.
- High efficiency: ultraviolet laser marking machine marking speed is very fast, can be completed in a short period of time a large number of marking tasks.
- Wide applicability: UV laser marking machine can mark on a variety of materials, such as plastics, ceramics, glass, metal and other materials.
- Strong durability: the laser of the UV laser marking machine has a long life and can work continuously for tens of thousands of hours.
- Environmental protection and energy saving: UV laser marking machine has low energy consumption and does not produce waste gas, waste water and other pollutants.
