Laser marking is a type of technology that relies on laser beams to mark or label a wide selection of materials. There is also an array of techniques used in laser marking, namely, staining, foaming, engraving, removing, and annealing. The technique of choice for any material often depends on the quality of material and the finish required. 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. 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 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.
Laser marking machines also make use of the technique of 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. The use of this marking technique entails the use of certain materials like foils, laminates, films, coated metals, and anodized aluminum.
Staining is another method that laser marking machines apply. A certain kind of chemical reaction is created with the laser beam and the heat that it generates. From the material you have and using this technique, you get to have an array of color shades with just one material. You get variations in color shading depending on the unique chemical composition of the material or plastic that you select. 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 technique used if you want to etch an array of metals. An oxidation process becomes the result of using a laser beam on the metal surface. The different layers from the metal material will then go through different changes in color.
There are many advantages that you can explore from the use of laser marking machine. As you work with tiny geometries, one of the benefits of using this machine is that you can achieve high precision. Laser marking is a process that is permanent. You don’t expect the mark to fade away even if the material will get into contact with heat, acids, or abrasion. Since laser marking is efficient and fast, you can lower production costs and increase productivity with the use of these machines.
