Laser marking on metals, A fast technique full of benefits

In recent years, many new businesses have seen the light, all of them with the intention of offering something different to users. A market that has caught our attention, and that is booming, is that of using a laser system to make all kinds of marks on metals or other materials. Thanks to these marks, it is possible to better track these objects, components that in many cases end up inside vehicles, inside our mobile phones or whatever else comes to mind. There are many advantages offered by laser marking on metals, advantages that you can see on the portal we think it may be of interest to you, today we want to delve a little deeper into this type of business so that you can learn more about how it works and its advantages.


How does laser engraving on metals work?

Laser engraving on metals is a technique that allows marking any metal using a laser beam on its surface. For this, it is necessary to have a metal engraver that allows carrying out this type of action. Thanks to this, it is possible to work with an infinite number of shapes and materials, achieving very precise and fast results. All this has caused techniques such as mechanical engraving, plate stamping, casting or chemical engraving to go into the background.

Now, how does the laser work? Any laser is made up of three different components: external pump source, active laser medium, and the resonator. The first of them is responsible for conducting the external energy towards the laser. The laser medium is located inside the laser and, depending on its design, can be made up of a mixture of gases, a glass body or fiberglass. When transferred to the laser medium through the pump source, the energy is emitted as radiation. Finally, the resonator is responsible for amplifying the radiation. At the same time, only a certain amount of radiation can leave the resonator through the one-way mirror. This directed radiation is laser radiation.

Thanks to the versatility offered by the laser, it is used in different fields to perforate materials, welds, measurements and even operations. Areas such as electronics, medicine or defense already benefit from its characteristics.

What are its main advantages?

One of the most important advantages is that it is a very precise technique that offers greater legibility of the engravings. In addition, this procedure speeds up the operation and is less damaging to the object to be marked.

It is also important to note that with this type of engraving the material is not touched, which prevents damage that can end up breaking the product. To the above, we must add that it is a very flexible technique, being able to create engravings of all kinds, whether they are images, letters, numbers or any other code. Everything we can imagine can come true.
