One of the latest technologies used in marking or labelling different materials with the use of laser beams is laser marking. 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 commonly used materials include laminates; plastics like ABS and polycarbonate; metals like platinum, bronze, copper, titanium, silver, gold, and stainless steel; and foils. If you have plans of purchasing a laser marking machine, you have to know what your options are. 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. These machines specifically heat the top surface of your material of choice, which then melts and evaporates. 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.
Removing is another technique used in laser marking machines. 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.
Staining is another method that laser marking machines apply. The heat coming from the laser beam in this process creates a certain chemical reaction. 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. So, if you use this machine on any plastic material with light color, you will see dark marks on the surface of the material from the soot-like particles created by the laser.
Your laser marking machine is also capable of creating annealing marks. This technique enables etching an wide selection of metals. 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.
There are many benefits to using laser marking machines. One of these benefits is getting high precision from the tiny geometries you are working with. 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. Because of the efficiency and fast nature of the process, you can expect a decrease in production costs and an increase in productivity through the utilization of these machines.
