Understanding Laser Marking Machines and What They Can Do for You

Laser marking is a type of technology that relies on laser beams to mark or label a wide selection of materials. You can also choose from various kinds of laser marking techniques such as foaming, engraving, annealing, removing, and staining. 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. It helps if you know what are your choices before you consider checking out and buying any laser marking machine in store. Here are some of your marking machine options to choose from and find out more about.

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. 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. Coated metals, foils, laminates, anodized aluminum, and films are the preferred materials using this marking technique.

You also have the so-called technique of staining when it comes to laser marking machines. A certain kind of chemical reaction is created with the laser beam and the heat that it generates. With this technique, you get variations of color shades in one material. The color shading will depend on the chemical composition that is present in the material like plastic. 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. If you use a laser beam on the metal surface, you create an oxidation process. 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. One of these benefits is getting high precision from the tiny geometries you are working with. The laser marking process is a permanent one. 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.
