How laser engraving works and its advantages

How does laser engraving work? | FAQ Trotec Laser

In addition to being used in the welding industry, laser technology can also be used to cut, engrave and mark objects. As the laser can cut metal of various thicknesses and remove small amounts of material, it can be used on a wide variety of objects, creating precise results and aesthetic effects in a short period of time, without the risk of damaging or deforming the various parts of the treated object.

The workings of laser marking

With Laser engraving on metals marking, the marking machine emits a laser beam that is directed at a small portion of the object to be engraved, marked or cut. This method provides precise and rapid results: the laser beam is conveyed to a small part of the surface of the object to be engraved, marked or cut. By transferring heat to the material that constitutes the object, the laser beam transfers energy. Using this method, an incision is made, whose depth can be adjusted according to the needs.

It is also possible to apply the same technique to obtain other results, such as deep engraving or marking, by increasing the intensity of the laser and lengthening the exposure times to the laser beam. By completing this step, a true excavation will be obtained that may be small in diameter, but still deep, as opposed to markings made with other mechanical means.

Lastly, the laser can be used to cut metal by repeatedly passing the beam over the same region. By removing increasing amounts of material this way, you can produce a cut little by little.

Engraving and marking with lasers tend to be very precise and defined. Lasers can obtain thin engravings and can be used to work on fragile or delicate surfaces, as well as to operate on surfaces that are difficult to reach with traditional engraving tools. However, laser engraving’s potential does not stop there: using this technology in combination with software allows for the production of highly refined aesthetic results. Since the laser beam that hits the metal can be calibrated in order to achieve the desired result, bas-reliefs can be created of varying depths, or even to change the colour of the starting material.

 

Laser marking applications

A large variety of metals can be engraved or cut with laser marking, including:

  • Effortlessly
  • Gold
  • Platonic
  • Metal
  • Titanium
  • Playland
  • Metals
  • Therefore, etc.

Laser marking: what are the benefits?

From an aesthetic point of view, laser marking provides numerous advantages, since it enables flawless results. Precision of the laser ensures complete and permanent engravement of the object, without smudges in the incision or abrasions to the treated surface. It allows for extremely clean and clear results as well as the ability to treat even precious and delicate objects without risking damage.

Furthermore, laser marking dramatically reduces processing times, which is another advantage to laser marking. Lasers can quickly engrave a wide variety of materials, and if the marking machine is equipped with appropriate software, it can significantly increase productivity in terms of production speed and variety of processes it can offer customers. By acting on the power of the beam, the laser can also produce excellent results on normally difficult to treat surfaces, or even on materials that are resistant to engraving. Moreover, laser marking allows for long-lasting results: the marked objects won’t corrode or deteriorate, and hence the engraving will always be visible and clear, as required by the regulations defining the quality standards for industrial production.
