There was a time when laser marking technology, as it is known today, was mainly used by industrial manufacturers, however now, it is used by small businesses, makers, hobbyists, and product designers in a wide range of ways. Laser manufacturing is one of the most technologically advanced forms of manufacturing in the world, regardless of the application.
Can you tell me if you’re familiar with laser marking technology? With the information provided in the following article, you will be able to get started with laser marking right away. This article explains laser marking technology and how it works.

A variety of laser marking methods
According to the application, laser markings can be of many types. Laser marking can be done in a variety of ways. The following are a few examples.
Using a laser beam, laser annealing is a process that uses focused heating to create marks on metal surfaces or materials. By focusing the beam, the metal changes color during the heating process, resulting in structural changes. As a result of this process, green, red, and yellow markings can also occur depending on how much heat is applied.
The color marking technique is the most common method used when laser marking stainless steel materials. This technique is based on the chemical composition of the material. Metal materials are produced using pigments that interact with laser beams during the manufacturing process.
Photoelectric effects are used to mark materials by changing their colors.
Engraving is a laser marking method that makes it easy to create marks on coated materials. The laser beam must be focused on the material in order to reveal the substrate layer. Color contrast can be created between two layers if their shades differ.
Lasers are very effective when it comes to marking aluminum that has been anodized or other coated materials. Most commonly, stone engraving has been done on materials such as ceramics, metals, and plastics.
A foaming technique is used to create light color markings when carbonizing will not work. Bubbles form when gas bubbles are emitted from a material’s surface when it is heated to a melting point.
Light is reflected backward by oxidized gas bubbles, resulting in foam. Since the mark created is highly contrasted from the other surfaces, it rises above them. This discoloration effect is visible on polymer surfaces. Foaming laser marking works best on dark-colored objects.
Different markings for daytime and nighttime
In-depth laser marking applications
The use of laser marking is beneficial to a wide range of industries and sectors. Many different industries use laser marking for various purposes, such as barcoding, QR coding, identifying serial numbers, marking copyright, and encoding logos.
With this method, plastics and metals are given date values. Material identification is also done with the help of this device, in addition to engraving best before dates. In addition, because it offers high security, it is used when creating smartcards and IDs to prevent fraud.
Indirect benefits of laser marking
There are different ways in which laser marking benefits different industries. We can see that laser marking has several advantages when we look at some of its benefits. Despite the use of delicate graphics, lasers produce highly accurate markings. There is no difference in font style or geometry when it comes to marking information. Moreover, laser marking makes sure high-quality marks are consistently applied to materials.
The fastest marking method available today is laser marking without a doubt. Profitability is increased significantly through increased productivity and reduced costs. Laser marking produces permanent marks that are resistant to abrasion, acid, and heat. Marking materials with laser settings that are appropriate will not damage them.
