Fibre laser marking machine and UV laser marking machine are two types of laser marking machine, but also the most used in the market at present, the most common two types of laser marking machine, so what is the difference between fibre laser marking machine and UV laser marking machine? What are the advantages of fibre laser marking machine? Here we come together to understand the knowledge of the laser marking machine.
First, the difference between fibre laser marking machine and ultraviolet laser marking machine

Fibre laser marking machine and ultraviolet laser marking machine is the main difference between its application areas, core components and processing principles.

1, the core components of the laser is different

Ultraviolet laser marking machine: the use of 355nm ultraviolet laser research and development, the machine adopts the third-order cavity frequency doubling technology with infrared laser comparison, 355 ultraviolet light focusing spot is extremely small, can reduce the mechanical deformation of the material to a large extent, and processing thermal impact of small.

Fibre laser marking machine: the use of 1064nm wavelength.

On the laser wavelength, the shorter the general wavelength, the laser out of the focus spot is smaller, the higher the precision will be, the processing of the formation of the heat-affected zone is also smaller, the processing effect is also more exquisite.

2, different processing methods

Ultraviolet laser marking machine: ultraviolet laser processing is called "photo-etching" effect, "cold processing" with a very high load energy (ultraviolet) photons, can interrupt the material (especially organic materials) or the surrounding medium within the chemical bond to make the material to non-thermal processes occurring Destruction. It does not produce heating or thermal deformation of the inner layer of the processed surface or the neighbouring area, which makes it very suitable for fine processing.

Fibre laser marking machine: through the laser beam will surface material evaporation to reveal the deep material, or through the light energy caused by the chemical and physical changes in the surface material and "engraved" traces, or through the light energy to burn off part of the material, showing the required etching of the pattern, text, bar codes and other types of graphics, suitable for metal products processing.

3, different areas of application

Fibre laser marking machine: cost-effective, basically adapted to all types of metal surface laser marking. Because of the heat generated by its beam, not for high-precision special materials marking.

Ultraviolet laser marking machine: especially adapted to ultra-fine processing of the high-end market, cosmetics, pharmaceuticals, video and other polymer materials, packaging bottles surface marking, the effect is fine, marking cleaning and solid, better than inkjet coding and non-polluting. Flexible pcb board marking, scribing. Silicon wafer microporous, blind hole processing. Which 80% of the market data line, adapter marking from the ultraviolet laser marking.
