The laser marking machine is a versatile mechanical equipment that can engrave various materials, such as glass, plastic, wood, silver, etc. The principle is to use a high-energy laser beam to chemically vaporize and burn off the surface of the object to be processed, so as to permanently mark the surface of the object to be processed. The laser marking machine can easily mark. Standard processing. When it comes to this, some friends may wonder whether it meets the metal standard? Metal is an inert substance, relatively soft, laser marking machine factory will explain to you.

1. Laser marking by heat treatment.

In this way, the fiber laser marking machine uses the high-density energy source of the laser beam, that is, the energy flow concentrated by the laser beam, to irradiate the surface of the workpiece and the surface of the workpiece. The object absorbs this energy flow. The process of generating thermal excitation in the irradiated area, thereby increasing the temperature of the surface or outer layer of the processed object or the atlas coating, leading to a series of changes, such as melting, evaporation, ablation, etc. The process of marking on the processing object is realized.

2. Cold processing laser marking.

It refers to high-energy ultraviolet photons, which destroy the chemical bonds inside the processed object or the chemical bonds of the surrounding medium, so that the processed object is destroyed by non-thermal processes. This marking process affects the processed objects. The inner layer and nearby areas of the object will not be affected by heating and deformation. For example, in the electronics industry, substrate materials are deposited with thin films of chemicals. These two different methods can complete the laser marking process. .

The reason why laser marking machines are so popular is largely due to their wide range of applications and excellent performance. With the prosperity of the market economy, the demand for food, chemical and medical fields is increasing. We believe that in the next few years, marking machines will still have an irreplaceable leading position in China!
