How should we distinguish the types of laser marking machines?  Laser marking machine can almost be used in all walks of life. The production of modern products cannot do without the help of laser marking machine.

The rapid development of laser marking machine technology has produced many different types of products.

Including UV laser, fiber laser, CO2 (carbon dioxide) laser marking machine, etc.

How should we distinguish the types of laser marking machines?  1, UV laser marking machine   UV laser marking machine relies on laser energy to destroy atoms or intermolecular bonds, making it a small molecule to evaporate and evaporate.

Because of its extremely small spot size and processing affected area, ultra-fine marking and special material marking can be carried out.

  2, fiber laser marking machine    fiber laser marking machine uses fiber laser to output laser, and then realizes marking function through high-speed scanning galvanometer system.

The optical fiber marking machine has a high photoelectric conversion rate, and can engrave metal materials and some non-metal materials. It is mainly used for depth and smoothness.

In areas with high fineness, bitmap markers can be used to mark beautiful patterns on metal and plastic surfaces.

  3, CO2 (carbon dioxide) laser marking machine    CO2 laser marking machine through the laser beam through the beam expansion, galvanometer, focus, by controlling the deflection of the galvanometer to achieve high-performance laser equipment marking.

The CO2 laser is a gas laser with a wavelength of 10.64um in the infrared band.

The CO 2 gas is charged into the discharge tube as a medium for generating laser light.

When a high voltage is applied to the electrode, a glow discharge is generated in the discharge tube and gas molecules are released.

After amplifying the laser energy, the laser forms a laser beam for processing materials, and the path of the laser beam is automatically changed by a computer-controlled galvanometer to realize automatic marking.

That is to say, the laser beam is irradiated on the surface of the material, and the light energy is instantly converted into heat energy, so that the surface of the material is melted or even evaporated immediately, thereby forming a mark.

How should we distinguish the types of laser marking machines? Different types of marking machines have different wavelengths.

Regardless of the type of laser marking machine, its application range has certain limitations. Therefore, in practical applications, do not use laser marking equipment to laser mark various materials.
