As the name implies, laser marking is a kind of technology that uses laser beams to mark or label an array of materials. There are different kinds of laser marking techniques used nowadays from annealing, foaming, removing, staining, and engraving. The technique that one prefers to apply to the material often depends on the quality of the material as well as the required finish. Foils; metals like silver, bronze, copper, stainless steel, titanium, gold, and platinum; laminates; and plastics like ABS and polycarbonate are some of the most seldom used materials. It helps if you know what are your choices before you consider checking out and buying any laser marking machine in store. If you want to find out which marking machine is right for you, read on.
A common laser marking machine option is the laser engraving machine. How these machines work is they heat the top surface of the material in question, which then proceeds to melt and evaporate. This process is the most efficient and fastest method of removing material with the use of a laser beam. After removing the material, the machine will be leaving behind a clear impression of the preferred mark of the person or the company, which can be a text, logo, or design.
Another technique used by laser marking machines is removing. The whole process of laser removing entails the use of a laser beam to remove the uppermost layer of the material. This allows for the creation of a contrast in the color throughout the various layers of the material. Coated metals, foils, laminates, anodized aluminum, and films are the preferred materials using this marking technique.
Staining is another method that laser marking machines apply. Heat from the laser beam enables the creation of a certain kind of chemical reaction. This technique allows for the creation of different shades of color with the material. The color shading depends on the chemical composition of the plastic or material that you choose. For instance, if you must use this machine on a light-colored plastic material, the laser beam will leave dark marks on the surface form the soot-like particles that it creates.
Your laser marking machine is also capable of creating annealing marks. This is a special technique that you use on a variety of metals for etching. If you use a laser beam on the metal surface, you create an oxidation process. This then leads to a change in color of the various layers in the metal materials.
The use of laser marking machines benefits you in more ways than one. One of these benefits includes achieving high precision when you are working with tiny geometries. The laser marking process is a permanent one. Even if the material comes into contact with heat, acids, or abrasion, the marks will never fade. Since laser marking is efficient and fast, you can lower production costs and increase productivity with the use of these machines.
