The difference between fiber laser marking machine and UV laser marking machine:

1. Different lasers

The fiber laser marking machine uses rare earth-doped glass fiber as the gain medium laser, and the laser wavelength is 1064nm. The UV laser marking machine uses UV laser with a wavelength of 355nm.

2. Different working principles

Fiber laser marking machines use laser beams to make permanent marks on the surface of various materials. The function of marking is to expose the deep material through the evaporation of the surface material, or to "carve" traces through the physical changes of the surface material caused by light energy, or to burn off part of the material through light energy to display the pattern, text, or barcode to be etched. and other types of graphics.

UV laser marking machine is a series of laser marking machines, so the principle is similar to that of laser marking machines, which use laser beams to make permanent marks on the surface of various materials. The function of marking is to directly break the molecular chains of substances through short-wave lasers (unlike the evaporation of surface substances produced by long-wave lasers to reveal deep substances), revealing the patterns and text to be processed. etching.

3. Different processing methods

Fiber laser marking machines use lasers for physical marking. Laser physical processing method mainly processes the surface of products and materials, which belongs to thermal processing. UV laser marking machines use cold processing, a chemical processing method, and the laser chemical processing method uses lasers to penetrate deep into product materials for processing.

4. Different application fields

Fiber laser marking machines are basically suitable for laser marking on various metal surfaces. Due to the heat generated by its beam, it is not suitable for high-precision marking of special materials. like:

Widely used in integrated circuit chips, computer accessories, industrial bearings, watches, electronic communication products, aerospace devices, various auto parts, home appliances, hardware tools, molds, wires and cables, food packaging, jewelry, tobacco, military, and other sites Graphic and text marking, batch production line operations.

UV laser marking machine: Especially suitable for the high-end market of fine processing. like:

A. The surface marking effect of packaging bottles made of polymer materials such as cosmetics, medicines, and excipients is good and has strong cleaning power. It is better than inkjet coding and has no pollution;

B. Marking and scribing of flexible PCB boards; processing of micro-holes and blind holes in silicon wafers;

C. LCD liquid crystal glass QR code marking, glassware surface drilling, metal surface coating marking, plastic buttons, electronic components, gifts, communication equipment, building materials, etc.

What are the advantages of fiber laser marking machines and UV laser marking machines?

1. Advantages of fiber laser marking machine:

A. Good beam quality

The laser beam is thin, the processing material consumption is small, and the processing heat affected zone is small. The markings on the markers are permanent and will not fade due to environmental influences. The annotated graphics are exquisite and beautiful.

B. Long service life

Fiber laser technology can greatly extend the service life of equipment (compared to DPSSL), up to 100,000 hours.

Fiber lasers have other advantages: because the laser medium of the fiber laser is a guided wave medium, it is highly efficient; the fiber laser is easy to connect to the fiber transmission system and has high efficiency; the fiber core can be made very thin and high power density can be achieved; fiber heat dissipation Due to its good performance, the fiber laser has high conversion efficiency and extremely low threshold; the fiber laser has a wide output wavelength range, from 400 to 3400nm, which can meet the needs of various applications. It has good application prospects in military, medical and other fields.

C. Energy saving and environmental protection

The electro-optical efficiency of the fiber laser marking machine is as high as 28%, which greatly saves power consumption during operation and saves operating costs.

Fiber laser marking machine is pollution-free and noise-free.

D. Low maintenance cost

Since fiber lasers do not have optical lenses in the resonant cavity, they have the advantages of adjustment-free, maintenance-free, and high stability, which are unmatched by traditional lasers.

2. Advantages of UV laser marking machine:

A. Can carry out ultra-fine marking and special material marking

Due to the extremely small focus and small processing heat-affected zone, UV laser can perform ultra-fine marking and marking of special materials. It is the first choice for customers who have higher requirements for marking effects.

B. Cold working method is more effective

Ultraviolet laser processing becomes cold processing because the high-energy molecules of ultraviolet photons directly separate the molecules on the metal or non-metal materials that need to be processed. However, this separation causes the molecules to separate from the material. This way of working does not generate heat.

On the basis of cold working, the effect of processing product materials will get better results and better development. Because when using cold laser processing, the probability of material influence is reduced to one percent, thus reducing the advantages of processing. Get all apps.

C

The thermal impact area of the UV laser marking machine is very small, will not produce thermal effects, and will not cause the problem of material burning.

D

Ultraviolet lasers are mainly low-power, with stable performance, small size and low power consumption.
