What difference between fiber/CO2/UV laser marking machines?

Fiber laser marking machine

The fiber Laser Marking Machine uses a fiber laser to strike a laser beam on the surface of a variety of different materials. The surface material is physically or chemically changed through light energy, thereby engraving patterns, trademarks and texts. Permanently marked marking equipment. Its components include: fiber laser, laser galvanometer, field lens, industrial computer, display, cabinet, control switch, power supply, ruler and lifting shaft, etc. MOPA laser marking machine also belongs to the type of fiber laser marking machine.

 

CO2 laser marking machine

The CO2 Laser Marking Machine (CO2 Laser Marking Machine) uses a gas laser with an infrared light band of 10.64μm. The CO2 gas is charged into the high-pressure discharge tube to generate glow discharge, which causes the gas molecules to release the laser, and the laser energy is amplified to form a pair The laser beam for material processing, the laser beam vaporizes the surface of the processed body to achieve the purpose of engraving.

 

UV laser marking machine

The UV Laser Marking Machine uses a 355nm UV laser to strike the laser beam on the surface of a variety of different substances, and directly break the molecular chain of the substance through a short-wavelength laser, thereby engraving patterns, trademarks and texts. Permanently marked marking equipment.

 

The differences between optical fiber, carbon dioxide and ultraviolet laser marking machines are as follows:

1. Different laser source: fiber laser marking machine adopts fiber laser, CO2 laser marking machine adopts CO2 gas laser, and UV laser marking machine adopts short-wavelength ultraviolet laser.

 

Ultraviolet laser is a technology that is completely different from carbon dioxide and fiber laser technology. Ultraviolet laser is also called blue laser beam. This technology has a low calorific engraving ability. It does not heat materials like fiber and CO2 laser marking machines. The surface is cold light carving.

 

2. The laser wavelength is different: the laser wavelength of the fiber marking machine is 1064nm, the laser wavelength of the carbon dioxide laser marking machine is 10.64μm, and the laser wavelength of the ultraviolet laser marking machine is 355nm.

 

3. Different application fields: CO2 laser marking machine is suitable for engraving most non-metallic materials and some metal products like paper,wood,leather,cloth......fiber laser marking machine is suitable for engraving most metal materials and some non-metallic materials, and UV laser marking machine can Clearly mark all plastics and other materials that have an adverse reaction to heat. It is especially suitable for applications such as marking, micro-perforating, high-speed division of glass materials, and complex pattern cutting of silicon wafers and wafers for food and pharmaceutical packaging materials.
