Everyone has been there. You’re looking for something in your home, but you just can’t find it.
Wouldn’t it be nice if every box and container in your house were marked with exactly what’s in it? You could use a pen or marker, but those wear off over time.
If you’re looking for a more permanent solution that won’t damage your product, laser marking might be right for you. Keep reading to learn about how laser marking works and some of its advantages.
How Does Laser Marking Work?
Put simply, laser marking systems use lasers to make permanent marks on materials without damaging them. The word laser is an acronym for light amplification by the stimulated emission of radiation.
Although they have been around for almost a century, lasers remain a mystery to many people. In short, when light hits an atom, one of the electrons can go to a higher energy level. When it goes back down to its original state, it releases light.
This is stimulated emission and is the principle behind how lasers work. When light from the laser hits a material, its energy changes the material in different ways depending on the method.
Types of Laser Marking
There are several different types of laser marking systems that are better for certain materials or processes. One big distinction is between fiber lasers and gas lasers. A fiber laser marking machine uses fiber optics to produce a laser beam.
Fiber lasers, also called solid-state lasers, include rare-earth elements which makes them more expensive but also more versatile. These lasers are perfect for things like marking metals because they produce light at a wavelength that metals react to.
Gas lasers use gases such as helium and neon or carbon dioxide to produce a laser beam. This technology is older and more developed, and it is useful for marking things like organic materials and plastics.
In addition to these two main types of lasers, there are several types of marking procedures that are better for different laser applications. Laser engraving makes deep marks in a material by turning part of the material into dust.
Laser etching is similar to engraving but is not as deep. It melts the material slightly to make a mark.
One type of surface laser marking is annealing. This process involves a chemical reaction with the material that doesn’t damage it.
Advantages of Laser Marking
There can be many advantages to having a laser marking machine. They mark materials with incredible speed and precision. Lasers are typically controlled by a computer and the location where they hit the material can be very small.
This means you can make marks in a material that are very small and controlled. Laser marking systems are useful for sensitive materials that can’t be damaged or can only be damaged in limited ways.
This means you can mark things like plastics without using solvents or other additives which is important in the medical industry. For more information about laser marking systems, check out https://www.lasitlaser.com/laser-marking-flyuv/.
