You can find a lot of plastics and
metals that are engraved with their type, model number and manufacturers. Have
you ever wondered how are they engraved? Obviously, not by
hand, it is next to
impossible to engrave so neatly and so precisely yet so small. Laser engraving
is an extensive technique used in many industries.
Like the name suggests, laser
engraving uses laser for marking materials. The marks are quite permanent. In
other words, they do not wear off that easily with water and solvents.
The technology includes many marking
techniques like: laser bonding, printing and hot branding. The tip of the laser
device acts like a pencil’s tip, tracing the patterns of the material. The
materials can be metal, plastic, stone, glass, and even wood. Because of its
vast capabilities, it is one of the most trusted and used engraving
technologies today, promising fast work and accuracy.
Some of these materials produce
excellent results. For example: for metals, anodized aluminum is a good choice,
however not for outdoors materials as they are bound to spoil. In fact, most
engraved metals are for indoors. If you want to engrave outdoor materials,
considerations should be made.
As for woods, hardwoods are used as
they do not vaporize easily. In plastic, acrylic lasers work well. If we look
at stone and glass, they fracture exposing natural grains.
It is gaining popularity in jewelers
as well. The precision with which laser engraving works is surprising. You can
now go for engraving on the engagements rings, all thanks to the laser
technology.
In industries, laser engraving has
reached quite high. In the medical sector, it is used in stainless steel
implants, surgical tools, printing labels, and fluid bags; these are just a few
of the listed examples. As for pharmaceutical industry, laser engraving is used
in package films, blisters packs, and glass ampoules. But, electrical industry
has benefited the most from it. They use laser engraving in IC packages, PC
boards, plastic housing, ceramics, lead frames and wire marking etc.
With the progress of technology,
laser engraving has obtained new heights. It is one of the most reliable and
efficient process. Laser engraving has a lot of benefits. Heat Sign is the name
to look out for, when you want to know more about laser engraving. For more information visit our website
