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. For those who want to choose the right marking machine, check it out.
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. The use of a laser beam to remove material is the most efficient and easiest through this method. 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. In laser removing, the uppermost layer of the material is removed using a laser beam. This creates a contrast of color with the variations of layers present in the material. The materials of choice for the use of this technique include anodized aluminum, foils, films, coated metals, and laminates.
Staining is another method that laser marking machines apply. Heat from the laser beam enables the creation of a certain kind of chemical reaction. With this technique, you get variations of color shades in one material. You get variations in color shading depending on the unique chemical composition of the material or plastic that you select. For example, if your plastic material is light in color, the laser beam will create soot-like particles that will provide a dark-colored mark on surfaces.
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.
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. 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.
