Introduction of CNC Laser Marking Machine

• Fiber Laser Marking Machine

The fiber laser marking machine adopts a fiber laser generator, also known as Solid-State Laser (SSL) equipment, working wavelength standard is 1064nm. With the features of easy operation, fast marking speed, high marking accuracy, 100,000 hours service time and free maintenance, fiber laser marking machine is an ideal marking solution for variety of products processing.

• CO2 Laser Marking Machine

The CO2 laser marking machines adopt CO2 gas in a sealed-off metal tube as the laser generator. It is gas laser marker machine that are based on carbon dioxide gas mixture, due to their wavelength (9.3 µm/10.6 µm), this type of CO2 marking machines are commonly used for marking and engraving most non-metallic materials, such as wood, glass, ceramic, crystal, jade, acrylic, PVC, paper packaging, rubber, plastic products, garments, cloth, fabric, leather, film, ect. 

• MOPA Laser Marking Machines

The MOPA laser marker machine is a kind of fiber laser, the term MOPA is an abbreviation for Master Oscillator Power Amplifier. The main features of MOPA fiber laser are that the laser marking frequency and pulse width can be independently controlled. 

 

As MOPA fiber laser can be modified the frequency and pulse width, through these two laser marking parameter adjustment collocation, it can achieve constant peak power output.

 

MOPA laser with the advantages of first pulse is available, the pulse width modulation is wider, and the response speed is faster, which enables them to work with a large number of materials than the fiber laser marking machines.

 

Compared with fiber laser that can only mark metal materials, MOPA laser also can also mark for some non-metal materials. For some special materials marking, MOPA laser marking will show you some unexpected results such as color marking on stainless steel, black color marking on anodized aluminum, high contrast marking on plastics, 0.1mm smaller text marking , depth marking by high power MOPA generator, stripping anode, stripping coating, semiconductor and electronics industry, plastic and other sensitive material marking and PVC plastic pipe industry.

• UV Laser Marking Machines

The UV laser marking machine is a type of Ultraviolet (UV) laser marker, working with a 355nm wavelength UV laser generator. The wavelength of a UV laser is one-third of standard wavelength lasers, and thus UV lasers are also referred to as third-harmonic generation (THG) lasers.

 

UV laser marker is a "cold laser marking" method, the UV laser beam diameter is only 20 μm after focusing, there is no significant thermal influence next to the slit and no damage to the materials caused by the heat generated.

 

Compared with the fiber laser marking machine and CO2 laser marking machine, the main advantage of the UV laser marking system is the multifunctionality and capacity of engraving or cutting over different materials, UV laser marking machines not only can mark on all the metal materials but also can mark all the nonmetal material. 

 

Moreover, due to the high-quality laser beam, the UV laser marker is designed as the best marking solution for frosted effect glass, plastic color marking and some other high-contrast and ultra-fine effect marking. 

• 3D Dynamic Laser Marking Machines

3D laser marking machines is a dynamic marking system working with auto-focus function, which can be equipped with optical fiber and CO2 laser generator. It is a advanced dynamic laser processing solution that creates a amazing 3D logos, patterns, designs on non-flat surface and objects with different heights.  

 

The 3D laser marker machine is composed of 3D marking software, auto-focus system, dynamic galvanometer, field lens and laser generator. Compare to ordinary 2D laser marking machine with 2 mirrors, the 3D laser marking machine has 3 mirrors, and the third mirrors can automatically move forward and backward when the machine is marking. Under the controlled of 3D marking software, the machine will automatically change the marking position and focus length of laser beam on each 3D coordinate.

 

Moreover, the maximum working size of ordinary 2D laser marker machines is 300mm×300 mm, but 3D laser marking machine with dynamic focusing laser Scanning System can provide you with more processing areas ranges from 500mm×500 mm to 1600mm×1600 mm.

 

Unlike the simple laser marking machines that can only be used for 2D effect, 3D laser engraving technology can also mark on round shapes, cylindrical shapes, conical shapes, parts with concave or convex portions, triangular shapes, and sloped surfaces. It is also an idle laser processing solution for depth marking and 3D relief engraving on metal or aluminium materials.

• Large Size Laser Marking Machines

Large size laser marking machine adopts splicing marking technology specially for processing some big size materials. With the increase of big size projects, there are more and more large customized markings, but there is a marking area limit compared with the ordinary laser marking machine.
