The anti-counterfeiting function of the laser marking machine is also very powerful. Its marking code has a durable feature. It is engraved on the surface of the workpiece, and will not fade, nor be easily removed by friction. It is durable and clear. It can effectively prevent some unscrupulous businessmen from manufacturing counterfeit capsules and selling them on the market. A clear and lasting mark also plays a certain role in tracing the source, not only improving the efficiency of manufacturers in terms of quality and speed.
The importance of laser marking machine in the medical industry is growing day by day. With the new technology of laser marking machine or other changes in sensitive materials in the medical industry, the laser marking technology cannot stop. Only by continuously improving and developing its technology and improving its quality, can the laser marking machine make contributions to the medical industry and benefit the nation and society.
The "hot processing" laser beam with high energy density (it is a concentrated energy flow) shines on the surface of the material to be processed. The surface of the material absorbs the laser energy and generates a thermal excitation process in the irradiation area, which causes the temperature of the material surface (or coating) to rise, resulting in distortion, melting, ablation, evaporation and other phenomena of the optical fiber laser marking machine.
"Cold processing" refers to the (ultraviolet) photons with high load energy, which can break the chemical bond in the material or surrounding medium, so as to cause the material to be damaged by the non thermal process. This kind of cold processing has significance in laser marking processing, because it is not thermal ablation, but does not produce "thermal damage". It breaks the cold stripping of the chemical bond, so it does not produce heating or thermal deformation on the inner layer and nearby areas of the surface to be processed, for example, In the electronic industry, excimer lasers are used to deposit chemical films on the substrate materials, and narrow grooves are made on the semiconductor substrate.
Maintenance method of laser marking machine lens.
The lens of the laser marking machine head is large and exposed in the air, which is relatively easy to be damaged. It may affect the effect of the marking machine, but it may need to change the lens, which may affect the production. Therefore, attention should be paid to protecting the lens of the laser marking machine during the use process. In addition to paying attention not to touch with foreign matters during the use process, attention should also be paid to the cleaning of the mirror surface, and the UV laser marking machine.
