Difference between Metal Laser Marking and Fibre Laser Marking

Difference between Metal Laser Marking and Fibre
Laser Marking

At present, the widely used laser marking
machines in this market are fibre laser marking,
UV laser marking ones and CO2 laser marking
machines. These three markers can always cover
around all types of product marking applications.
They are also stated as current mainstream
marking equipment. Due to the application fields,
processing principles and core components will
not be the same. Therefore, there is going to be
a difference in the price as well. For example,
the price of the UV laser marking product is
around thrice that the fibre laser marking
machine. Before you get to purchase the one you
like, focusing on the features is important to
note over here.

Principle and laser generator
The current UV based metal laser marking machine
is developed with 355nm UV laser. This machine is
designed to use third order cavity multiplication
technology, when compared to the infrared one.
The light focusing spot is quite small, which can
easily reduce the mechanical deformation of
material and even the small processing thermal
effect. On the other hand, you have the fibre
version of the machine too, where the wavelength
is 1064nm. With regard to the current wavelength
of laser light, the shorter the length is the
higher accuracy and smaller will be the laser
spot. Moreover, the smaller the affected zone is
formed during processing, the more exquisite will
be the processing effect at the same time.
Advantages of the UV laser machine when compared
to fibre one
In case of the wavelength, the UV lasers will
have shorter ones than visible wavelengths.
Therefore, it is not quite visible to naked eye.
Even though, you cannot see these laser beams of
the metal laser marking, these shorter
wavelengths will make UV laser to focus in a
precise manner. Therefore, it helps in
maintaining the excellent position accuracy while
adding fine circuit based characteristics. Anothe
r important factor can chalk out the differences.
Along with the lower work piece temperature, the
higher energy photons in UV light will allow the
UV laser to be used in some of the larger scaled
PCB circuit board assemblies. You can always get
the best approach noted under barcode laser
marking for your use.

Application areas to deal with
In terms of fibre laser marking machine, it is
high cost effective in nature and made suitable
for marking all forms of metal surfaces. Mainly
because of its beam generated heat, it is not
that meant to be suitable for high précised
special material marking. Then, for barcode
laser marking, you have the UV laser one, which
is made suitable for higher end market of the
ultra-fine processing. It comes with fine
effects, and the mark is firm and clean. It is
always better when compared to ink coding without
any pollution. Going through the differences
will assume that metal laser marking is always
better when compared to the fibre one. Before
making the final choice, be sure to consult the
team for help.
