• Speed and durability are the factors that make
  laser etching suitable for marking applications.
• So, in this article, well learn everything about
  laser etching how does it work? What kind of
  materials can you etch? Why should you brand
  spare parts like Trumpf spare parts or Prima
  spare parts? What are the various types of laser
  etching? And how to implement it?
• Lets start by understanding the laser etching
  process.
• What is Laser Etching
• It is a process that melts the surface of the
  material and creates marks on it. It belongs to
  the category of laser marking that also includes
  laser engraving and laser annealing. Laser
  etching is highly versatile and can be used with
  most metals.
• It is mainly used to produce permanent markings
  such as data matrix codes, serial numbers,
  barcodes, and logos.

How Does Laser Etching Work Whichever laser
marking method you use, theres one thing common
in all. The laser beam is pulsed, which then
releases sudden bursts of energy at specific
time intervals. A 100W laser pulse can release
100,000 pulses within a second. Each pulse
consists of 1 millijoule of energy and can reach
a max of 10,000W power. In laser etching, the
metal requires less energy than engraving.
Hence, in etching, the pulses are more distant
compared to engraving. For marking, the beam
hits the surface, and materials absorb the
energy. It reflects most of it while absorbing a
proportion, converting it to heat. For laser
etching, the material should absorb enough heat
to melt the surface and expand.
When the beams energy temperature increases. At
is transformed to heat, the such a high tempera
ture, the
material becomes malleable, allowing its shape to
change. As the material cools down within
milliseconds, the surface roughness of the
material changes, making a permanent mark.

• Also, the color change occurs as a result of
  permanent marking. For high-quality, black and
  white make the best contrast.
• This is a generic process. However, each material
  would have its own course of the process. The
  process would be optimized and different from
  the general process.
• What Materials Can You Etch with Laser?
• Laser etching is a versatile process, and you can
  etch almost all the materials. Here are the few
  from the list of non-exhaustive.
• Aluminum
• Lead
• Magnesium
• Steel
• Steel Stainless
• Zinc
• Anodized Aluminum

Types of Laser Etching Laser You can only use
fiber lasers for laser etching. The reason is
that etching is a process used for metals and
thus reacts better with a fiber laser. To be
precise, the laser depends on the material you
want to etch and not on the marking process. But
why do you exactly need fiber lasers? Let us find
out! Lasers release beams and energy at specific
intervals. The material reflects most of the
energy while absorbs the remaining, converting
it to heat. For etching, the material should
absorb enough heat to melt the surface. Now,
fiber and Co2 lasers generate different
wavelengths, and each material reflects these
wavelengths differently. To maximize the heat
transfer, the material should absorb enough
wavelength. If you test it, you will find that
material absorbs fiber wavelength more
efficiently than Co2 lasers, making it a better
choice for marking materials.

Why you Should Choose Branded Spare Parts We
often talk about lasers how to choose lasers
and maintain them. But we forget that a spare
part or a consumable is what defines the further
use of that laser during a wear-and-tear. To
ensure that the marking quality is as precise as
it was in the initial stages, use spare parts
such as Trumpf spare parts. These branded parts
are high-quality, have better resistance, and
dont wear quickly. As in laser etching, the
energy release is high, and the spare parts
would ensure that they are high temperature
resistant and can withstand energy. How to
Implement Laser Etching Consult an expert that
offers laser marking machines and OEM laser
markers. Specify your requirements and take their
guidance about the same.
