How laser marking of a product works
The marker uses the intense beam of light that focuses on the surface of a certain object. In this way the laser beam creates the image on the surface to be machined, piloted with movable mirrors or with a plotter head.
Depending on the characteristics of the laser source, an instantaneous peak power density of several hundred kilowatts is delivered to the product, causing an instantaneous surface modification and thus etching the object.
The advantages of a laser marker for identifying goods
The main advantages, compared to the classic labeling, concern the absence of some elements such as:
This not only improves the result, but also affects the reduction of maintenance costs.
A second important advantage is related to durability, in fact, unlike many engraving techniques that cause the removal of a part of the material, laser engraving does not cause this removal. For this, the laser creates a change in the color of the material, resulting in a visible, practically indestructible mark.
With this production method, the labels are resistant to temperatures, abrasion, chemicals and adverse weather conditions, ensuring maximum protection against counterfeiting and fraud.
A very interesting advantage for all those who have to deal with the identification of a product with variable data, is the possibility of having an automatic or semi-automatic operation: in addition to the fixed layouts, with a special software module it is possible to import variable laser marking contents from Excel or XML files, etc… with simplicity.
Finally, the environmental impact should not be underestimated, since the technology does not use inks, solvents or other consumables, thus saving on the environment and costs.
