Laser marking is a type of technology that relies on laser beams to mark or label a wide selection of materials. There are different kinds of laser marking techniques used nowadays from annealing, foaming, removing, staining, and engraving. The quality of the material and the finish required are two factors that determine the preferred marking technique that will be used on any material. Some of the most popular materials used include metals such as stainless steel, silver, gold, bronze, titanium, platinum, and copper; foils; laminates; and plastics such as ABS and polycarbonate. Before buying any laser marking machine, you should know what you are your choices. Here are some of your marking machine options to choose from and find out more about.
Laser engraving machines are one kind of laser marking machine that you can buy. These machines are created to heat the top surface of the material, which then slowly melts and evaporates. This particular method is the most efficient and quickest way for you to remove material with the use of a laser beam. Once the material is successfully removed, you will find a clear impression that is left behind, often in the form of a preferred mark like a design, text, or logo.
Another technique used by laser marking machines is removing. In laser removing, the uppermost layer of the material is removed using a laser beam. This allows for the creation of a contrast in the color throughout the various layers of the material. The use of this marking technique entails the use of certain materials like foils, laminates, films, coated metals, and anodized aluminum.
Another commonly used technique in laser marking machines is staining. A certain kind of chemical reaction is created with the laser beam and the heat that it generates. 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.
Annealing marking is another type of technique you can use on your laser marking machine. This is a special technique that you use on a variety of metals for etching. You will be getting an oxidation process as a result of using a laser beam on a metal surface. The different layers from the metal material will then go through different changes in color.
The use of laser marking machines benefits you in more ways than one. As you work with tiny geometries, one of the benefits of using this machine is that you can achieve high precision. You get a permanent process from laser marking. You don’t expect the mark to fade away even if the material will get into contact with heat, acids, or abrasion. With the efficient and fast nature of laser marking, the use of these machines has the potential to decrease production costs and increase productivity.
