Hot and cold processing of laser marking machine

Author: Correct Pack -Laser Marking Machine Manufacturer

Laser marking machine is a multi-functional mechanical equipment that can mark various materials such as glass, plastic, wood, silver and so on. The principle is to use high-energy laser beams to evaporate, chemically react and burn the surface of the processed object, so as to permanently mark the surface of the processed object, and the laser marking machine can easily mark the surface. Having said that, some friends may have doubts. Can it hit metal materials? Metal is an inactive substance and is relatively soft. The manufacturer will explain to you below. 1. Thermal processing laser marking. This method is mainly that the fiber laser marking machine uses the high-density energy source of the laser beam, that is, the concentrated energy flow of the laser beam, to irradiate the surface of the processed object, and the surface of the processed object absorbs this energy flow, thereby generating The process of thermal excitation, thereby increasing the temperature of the surface or outer surface layer of the processed object or the coating of the album, resulting in a series of changes such as melting, evaporation, ablation, etc., thereby realizing the process of marking the processed object. 2. Cold processing laser marking. Refers to the high-energy ultraviolet light that destroys the chemical bonds in the processed object or the chemical bonds in the surrounding medium, so that the processed object is destroyed in a non-thermal process. This marking process will not affect the inner layer and nearby areas of the processed object due to heating and deformation. For example, in the electronics industry, depositing thin films of chemicals on substrate materials can accomplish the laser marking process in two different ways. The reason why laser marking machines are so popular is largely due to their wide application fields and excellent performance. With the prosperity of the market economy, the demand for food, chemical industry and medical treatment continues to increase. We believe that in the next few years, marking machines will still have an irreplaceable leading position! .
