Laser marking
metals such as
anodized
aluminum,
stainless steel,
brass, and
others is a very
common
industrial
application,
allowing users
in a range of
industries to
permanently mark
their parts and
equipment with
serial numbers,
barcodes, data
matrixes,
production
dates, logos,
and more.
Laser marking
equipment offers
abrasion-proof,
durable,
fraud-protected,
and thermally-
and
chemically-resistant
markings for any
type of metal.
The laser
marking process
is fast,
precise,
contact-free,
and extremely
flexible.
Trotec offers a
range of CO2,
Nd:YAG anf Fiber laser
marking systems
for metals:
CO2 laser
technology is
ideal for metals
such as anodized
aluminium, and
on coated or
refined metal
surfaces. CO2
lasers can also
achieve
annealing
effects using a
high output, and
can be used to
create
inscriptions on
bare metals by
applying a
special spray to
the metal
surface prior to
irradiation.
This method
leads to a very
robust,
long-lasting,
"burn-in" metal
marking effect.
CO2 solutions
Nd:YAG and
Fiber laser
solutions offer
direct marking
of metals,
resulting in
gravures or
merely an
annealing
effect,
depending on the
beam parameters
and the used
material.
