Laser is a kind of powerful invisible light which has the
capability to cut through metal, rocks, hard plastic etc. It’s the amount of
heat generated that allows it to cut through most of the surfaces. This kind of
micromachining has found its application in various different industries for
this main reason.
The others reasons to use laser engraving are precision and
it can work even in very small areas. Different techniques are used for various
different kinds of surfaces. For example, to engrave on glasses, thermal modes
are used whereas in case of plastics, it can be melted to give a new shape to
it altogether.
Advantages:
§
Precision: The
process of micro-identification is used in various different products to
engrave logos, designs, outlines and such various ID codes which maintain
certain standards. This kind of micromachining without causing any damage to
the products at all is only possible via the use of laser engraving . The
marking can be done on any surface of your choice and also stay permanently on
them, even on a surface which is composed of polymer blends. Also,
customization is so easy that that one can draw any shape needed.
§
Accuracy: As already
mentioned, there’re various different types of ID codes, logos etc. that are
etched on these products and they vary in their character sizes, fonts etc.
Everything is possible with the use of this kind of micromachining. Whatever be
the type of the surface, may be round, curved, flat, undulating, this kind of
micromachining can work on all of them. Even if you’re worried for the tiniest
working areas, the laser machines will provide you 100% accuracy.
Marking v/s Engraving:
When it comes to micromachining, both
laser engraving and laser marking
falls under it. But one needs to understand the thin demarcation line between
these two processes. In engraving, the part of the product where the etching is
done is completely removed.
But in case of marking, this doesn’t happen at all.
Actually, a new kind of material is applied on the product where the marking
will be done. The best part is both these two processes are simply flawless and
easy to use. But engraving holds the upper hand of the two techniques as it
lasts longer of the two and also is more easily customizable.
Safety Measures:
As a huge amount of energy is
generated in this entire process, accidents are quite common. Thus the workers
need to be highly careful while working with these devices. During the entire
course of action PPE or Proper safety and Protection Equipment should be worn.
If by mistake, your body parts come in contact with the laser beam during laser
engraving, your body may damage severely or you may have your limbs cut off.
