Can the highly regarded nanosecond Q-switched lasers source work on metal materials?

Laser marking machine can also be called ultraviolet laser marking machine, UV ultraviolet laser marking machine, ultraviolet laser laser engraving machine, ultraviolet laser marking machine Principle: Like ordinary fiber laser marking machine, it also uses laser beam to The surface of the substance is marked with a long-lasting mark. The reaction mechanism during ultraviolet laser processing is realized by photochemical ablation, that is, relying on the laser energy to break the bonds between atoms or molecules, making them small molecules gasified and evaporated. , The focusing spot is extremely small, and the processing heat affected zone is very small, so it can be used for ultra-fine marking and special material marking.

With the rapid development of laser equipment and the improvement of the power of UV laser marking machines, UV laser marking machines have been applied to the high-end market of ultra-fine processing, packaging of iPhone, cosmetics, medicine, food and other molecular materials with high laser marking machines. Bottle surface marking, flexible PCB board marking, dicing, silicon wafer micro-hole, blind hole processing, LCD glass, glassware surface, metal surface coating, plastic buttons, electronic components, gifts, communication equipment, building materials and many other fields.

The UV laser processing process is called the "photo-etching" effect. The "cold processing" (ultraviolet) photons with high load energy can break the chemical bonds in the material or the surrounding medium, so that the material is damaged by a non-thermal process. It has special meaning in laser symbol processing, because it is not thermal ablation, but cold peeling that breaks chemical bonds without the side effect of "thermal damage", so there is no heating or heat to the inner layer and adjacent areas of the processed surface. Due to deformation and other effects, the material processed by the fiber laser marking machine has a lubricated edge and a very low degree of carbonization.

Under the environment of industrialized large-scale automated production line, UV laser marking machine has become an industrial processing manufacturer because of its advantages such as light quality, high peak value, narrow pulse width, and small thermal influence during processing, under the condition of higher electro-optical conversion efficiency. The darling of marking, can meet the needs of industrial mass production.

Can the UV laser marking machine mark metal products? The answer is yes, so why not use the UV laser marking machine to mark metal products? The reasons are as follows:.

1. The cost of UV laser marking machine is higher. From the perspective of cost, it is more suitable to use fiber laser marking machine for metal products. The power of fiber laser marking machine is high, and cutting and engraving on metal products The strength is just right, and the price of the fiber laser marking machine is more affordable. Generally, you can buy a piece of equipment for more than 10,000 yuan.

2. The UV laser marking machine is mainly used for ultra-fine marking, such as some circuit boards, glass, electronic components, etc. Usually, these products have higher marking requirements. The UV laser marking machine uses a laser with a wavelength of 355nm, and the focusing spot is small. , for general sensitive materials, there will be no scorching and burning, and it can focus more accurately.

3. The power of the UV laser marking machine is small, and it is difficult to achieve the effect required by the manufacturer on metal materials. The power of the conventional UV laser marking machine is: 3W, 5W, 10W, 15W, etc., and the minimum power of the fiber laser marking machine is also 20W , and further up is 30W, 50W, and even 100W products are more common, the power determines the use of different fields, each has its own advantages.
