Main Differences between Etching, Marking, and Engraving

Portable Laser marking, engraving, and etching are usually considered same in application. It is primarily because all of these laser services offer a simple solution to permanent marking. All of these processes are confused because these add distinction to your products while taking the assistance of laser in the process. It is important to note that all these practices completely follow governmental regulation regarding the use of laser.

What Sets Them Apart?

While all these three practices give the same result and entirely comply with the government regulations, it is essential to understand the points which set them apart. The primary point of difference is the process that each one of them follows. What the process does to the surface that is being marked, the overall appearance of the mark, and last but not least, how deep the mark is and how durable it stands. A portable laser marking machine would always enjoy a vital portfolio given that the surface finish and durability of the mark are healthier
