The laser engraving it's a tool quite popular, given that It makes the work easier when making any type of engraving. It is often widely used in industrial sector because it allows them to leave permanent marks in order to protect intellectual property and personalize articles.

What is laser engraving?

laser engraving is a process that vaporizes the materials in the form of rays to engrave permanent and deep marks. This acts like a chisel, carving marks on the delete layers from the surface of the material. The laser works by hitting localized areas with massive levels of energy to generate the high heat necessary for vaporization.

The laser engraving technology It is commonly used to engrave metal parts that are exposed to different types of wear or treatments superficial. The most prominent feature of this process is the ability to engrave 2D codes that maintain high readability indices after post-process treatments. These treatments can be shot blasting, electroplating and heat treatments.

You can laser engrave a large variety of materials such as: steel, aluminum, anodized aluminum, lead, magnesium and zinc.

How is the proccess?

The laser engraving sublimates the surface of the material to create deep cracks. This means that the surface instantly absorbs energy enough to get past solid to gas until it becomes a liquid.

To achieve this process, the engraving system must generate enough power for the surface of the material to reach its vaporization temperature in milliseconds. You have to keep in mind that you are tools are quite powerful.

The materials vaporize into smoke when they reach certain temperatures, so we must take into account that the laser system is equipped with a smoke extraction to protect the workspace and a air knife to protect the laser lens.

Laser engraving in the industrial sector.

In it industrial sector the use has been implemented remarkably of various types of laser engraving. This allows them to leave permanent marks, in order to protect intellectual property and customize items. It also allows them to provide verifications and controls to avoid replicas or counterfeits.

  • It's a quick process It can be done in any type of metal.
  • The most frequent applications of the various types of laser engravings are in terms of security, identification and traceability.
  • Its use is very important for the improvement of operability of industrial companies.
  • They may be connected to a factory network. This makes it possible to monitor operations, perform system maintenance and remotely resolve any problems that may arise.
  • gives them an added value products by placing a unique engraving.
  • Laser engraving has been irreversibly implemented in those processes that need to place a identification on the products.

Factors that influence laser engraving.

There are several factors that influence laser engraving according to its procedure:

  • Pressure cuts and gases.

Depending on the depth level some are achieved more accentuated results or deep, or superficial engravings.

The laser engraving machine expels the gases through a cut slot that must be duly regulated.

  • Laser engraving machine power.

The power depends on laser engraving type, in addition to the surface with which you are going to work. Therefore, in each case a power is required.

  • Nozzle and focus diameter.

The dimension Of the piece to be recorded will determine the position in which it should be placed, taking into account the position of the focus.

  • Speed and projection of the laser.

Projection can be done by pulses or continuously, choosing the one that best suits what is intended to be achieved. The same is done with speed.

  • Degree of polarization.

With the degree of polarization, we refer to the waves that must be issued to be able to give the proper direction of cut, a determining factor in the quality of this.
