Now the laser technology has become increasingly mature, especially in the laser marking machine, both metal and non-metal industries can carry out marking. Laser marking is particularly suitable for processing. The images and texts marked by laser are exquisite and beautiful, and can not be wiped, and will not fade or benefit due to the long time. This can not only improve the product grade, but also play a role in preventing counterfeiting and counterfeiting.

In order to meet the needs of various industries, the laser marking machine has developed a series of demands. Different series are aimed at different materials in different industries, and the integrated cabinet planning is generally used for laser marking. Such planning makes the laser marking machine small in size and does not take up space.

There are mainly two kinds of laser marking machines, one is cold processing, the other is hot processing. These two kinds of processing skills are mainly aimed at different raw materials. Generally, hot processing is aimed at the metal industry, while processing is aimed at the plastic industry that cannot be heated.

Differences between laser marking cold processing and hot processing

Laser marking cold processing: cold processing is generally used on green light marking machines and ultraviolet laser marking machines. Cold processing is a new high-tech technology that has emerged in recent years. First of all, the surface of the workpiece is illuminated by a laser beam with high energy density. The surface of the raw material absorbs laser energy, causing non thermal damage to the material. As it is selected for cold processing, it will not cause baking, black edges, deformation and other problems to the workpiece.

Laser marking thermal processing: the high-energy laser beam selected for thermal processing shines on the surface of the workpiece, making its illuminated area produce thermal reaction, making its temperature rise to, reaching the baking, dissolution, evaporation and other phenomena, so as to achieve the target effect that we will eventually order. This kind of laser beam is mainly used for optical fiber laser marking machine, CO2 laser marking machine, semiconductor laser marking machine.

The cold processing method is still the hot processing method. The contribution of the laser marking machine to industrial symbols is irreplaceable. The advantages of the laser marking machine, such as high-quality graphics and text, inorganic press processing, no consumables, no noise, and the ability to achieve assembly line production, make it an indispensable member of industrial processing. Especially in the current electronic and electrical industry, the traditional symbol method simply fades and erases, It may lead to the ignorance of this product. For example, it requires a lot of manpower and material resources to test from scratch. It is now doomed that the laser marking machine replaces the traditional symbol method.
