Laser marking does not store energy

Why does surface energy of a laser-marked surface not change markedly?

Surface energy of a laser-marked surface (Figures 10.1 and 10.2) does not change markedly because of the small proportion of the involved surface. Table 10.2. Laser Marking Processes Figure 10.1. Examples of four types of laser marking on plastics . Figure 10.2. Laser marking using a letter mask .

How does a laser marking machine work?

The laser marking machine etches the workpiece by releasing pulsed laser beams on the workpiece surface. On hitting the surface, the material absorbs the beam and converts it to heat to melt the surface and raises it. The laser-etched surface requires less energy as it does not have depth, unlike laser engraving. Furthermore, they are more visible.

Is laser marking non-contact?

The marking system is non-contact as it uses a laser beam generated by a laser marking machine. The laser marking process depends on the laser technology you are using. Nevertheless, each laser technology can produce permanent marks on many materials. How Does Laser Marking Work?

What is laser marking?

Laser marking is a thermal process that employs a high-intensity beam of focused laser light to create a contrasting mark on the material surface. You might find these chapters and articles relevant to this topic. Some additives have an unusual effect as opposed to an additive like silica which acts strictly physically.

Why is laser marking important?

Laser marking techniques guarantee exceptional durability, especially on metal surfaces. This is because permanent marking is achieved through in-depth physical changes to the material. For some plastics, the marking may be less durable due to wear or chemicals. It is essential to choose the right surface treatments to ensure adequate longevity.

Are laser marking systems eco-friendly?

Laser marking systems do not use consumables such as chemicals compared to inkjet marking. As a result, there is a lesser chance of ejection of harmful materials into the environment. Furthermore, unlike dot peening, laser technology does not produce noise, making them eco-friendly.
