Laser marking is a type of industrial marking which uses highly directed beams of light to slightly alter the appearance and properties of a material surface. Read on for some of the benefits of using the technology to mark your products:

1. Reduced physical damage

Laser marking is a non-contact process, meaning the laser machine and the surface being marked do not touch anywhere in the process. Since physical contact is minimized, it reduces damage and abrasions on the material, saving you the need for additional procedures later on. Essentially, the only part that sustains any “damage” is the area being heated, but that damage is needed for the markings to show.

2. Laser markers are versatile

Laser marking is used in many industries, and this is made possible by the existence of different types of laser marking machines. Fiber and CO2 lasers are the two most popular laser markers due to being flexible, effective, and more practical than conventional marking technologies. The main difference between them is in how the beam is generated and the power and wavelengths produced.

Industries that make the use of laser marking include the automotive, medical, semiconductor, and aerospace industries.

3. It is relatively cost-effective

Compared to most other industrial marking techniques, laser marking is less costly when all factors are considered. The machines are significantly cheaper, and the fact that you can combine them with a digital automation system makes them suitable for someone who wants to save on labor costs. It is also worth noting that repairing a laser-marked print is much easier and less costly than repairing a laser engraved one.

4. It offers high precision

The laser marking process is incredibly precise, making it possible to mark small objects without compromising accuracy. For this reason, most circuit board manufacturers fancy laser markers over other printing methods to label their products. So, if you have a precise printing job that you need to do, then it would be wise to consider investing in a laser marker.

5. Faster output

Most laser marking service providers use automated systems in high-volume projects. An automated laser machine offers not only high precision but also high printing speeds, which is excellent for lengthy inscriptions.

6. Laser markers do not eat away the material

As stated above, laser markers use beams of light to change the properties of the surface being marked. No material is cut out, and the beams do not permeate through the material. The oxidation occurs on the outermost surface only, which not only simplifies the process of correcting typos and other errors but also makes it possible to use the method on thin sheets of metal or plastic without compromising their structure. That said, the color change takes place beneath the surface being heated, so the marking is bound to stay there permanently.

7. Eco-friendliness

This factor is not discussed often because the bulk of the population is hardly eco-conscious. Still, it is a significant factor, particularly if you are doing laser marking commercially or repetitively.

Laser marking does not produce any toxic chemicals. It also doesn’t eat away material from the surface, as is the case with laser engraving, so the production metal and plastic debris are minimized. Acid etching is the complete opposite of this, at least from an ecological point of view.

8. It can be used on a variety of materials

If you don’t know where exactly you are going to need a marker in the future, it is best to go with a flexible option. Laser marking technology can be used on a wide spectrum of materials, from structural steels to various aluminum grades, and can still produce high-quality markings.

9. Laser marking is a safe process

Compared to other marking and etching methods, laser marking is less hazardous to the person conducting the process, as it involves no use of chemicals or emission of toxic fumes. What’s more, the product’s safety is not compromised once the marking process is completed. Laser marking is used on dental and other healthcare equipment for this reason.

10. The markings are durable

Despite being less invasive, laser markings are permanent and retain their contrast for a long time. This is because they can withstand temperature fluctuations, acids, and abrasion. They are also water-resistant and fade-proof.

Endnote

These are some of the benefits of laser marking technology. If you are not sure about its compatibility with the material and product you want to mark, consider seeking an expert’s advice for a more guided decision.
