Understanding Laser Marking and Its Uses

Differences Between Laser Marking, Laser Etching and Laser Engraving

After government regulations and determination legible products of laser marking, laser engraving and laser etching are now very popular in industry and It can be used for all types of business and companies.

Each of three of these laser method is a good solution of permanent marking , suitable for guidelines and adding separation to your parts and products .

But what sets these three methods apart?

Although the three methods seem similar, there are just a few differences between them.

The differences between laser marking, laser etching and laser engraving are all working as marking surface, but the case is application method which how deep the laser goes and how it changes the overall appearance.

Laser marking change the surface of the material, on the other hand laser engraving and etching removes a portion of the surface area of material as its marks. Essential difference between laser engraving and etching is the depth to which the laser penetrates the surface.

Each type of laser marking, laser engraving and etching has its own applications methods and attributes that suitable for different jobs.

Basic introduction of Laser

“Laser” is an acronym which is actually “Light Amplification by the Stimulated Emission of Radiation” After many years, the laser has become one of the most indispensable manufacturing tools which is used in nearly all business sectors.

Raising the energy levels of the atoms In order to create a laser, you raise the energy level of the atoms to an excited condition, which causes them to release light while energy level of them decreasing too their original energy, or ground state.

What a Laser Does?

When we look at the second word in the acronym, we see  “Amplification”. This word helps we better understanding of what a laser is doing. When a light beam is created,  amplification of this light beam if focused to a small point that has a highly concentrated and high energy level .

Vibration levels of atoms determine level of light beam.  Low level of atom vibration at low energy level they create a weak light, on the other hand  while including more and more energy to the system, the light waves and light beam become  more concentrated. These types of light sources are working with a different way (i.e flashlight). For example flashlights can emit light with different wavelength from the same source. But lasers rays of all have the same wavelength and are adherent, as a result lasers create a powerful concentration of energy.

Where are Lasers used?

Lasers are one of the most sophisticated modern invention. Lasers are used in so many sectors in industry, such as:

  • Automotive
  • Industrial & Tooling
  • Textile
  • Electronics
  • Oil and Gas
  • Marketing packaging
  • Medical
  • Military and Defense
  • Aerospace
  • cargo sector
  • Furniture and much more

Each sector of industry has its own method and uses for lasers. For example In the manufacturing industry,  lasers are mostly used in a manufacturing way. It is variety of dairy tasks, such as drilling , measuring, cleaning, cutting, measuring, welding and sensing, as well as marking, engraving and etching.

Actually there are so many other methods to mark materials such as ink mark, color press etc. But you can’t get the same quality, or environmentally  and efficiently friendly markings, that you get with laser marking, engraving and etching ,
