Everything You Need to Know About Laser Marking Machines

As the name implies, laser marking is a kind of technology that uses laser beams to mark or label an array 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. Foils; metals like silver, bronze, copper, stainless steel, titanium, gold, and platinum; laminates; and plastics like ABS and polycarbonate are some of the most seldom used materials. If you have plans of purchasing a laser marking machine, you have to know what your options are. For those who want to choose the right marking machine, check it out.

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.

Removing is another technique used in laser marking machines. 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. The heat coming from the laser beam in this process creates a certain chemical reaction. With this technique, you get variations of color shades in one material. The color shading depends on the chemical composition of the plastic or material that you choose. 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.

The use of laser marking machines benefits you in more ways than one. One of these benefits is getting high precision from the tiny geometries you are working with. 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. Since laser marking is efficient and fast, you can lower production costs and increase productivity with the use of these machines.
