A laser marking machine is a device used to leave a permanent readable mark that can withstand harsh environmental conditions and be traceable at the same time. Some of the permanent markings that a laser machine can create includes; barcodes, QR codes, logos and UID codes.
What Is Laser Marking?
Laser marking is when a light beam interacts with the surface of a certain material and slightly alters its appearance or properties. This process is also referred to as laser coloration or laser dark marking.
How Do These Machines Work?
A laser machine moves a low-powered beam slowly across a material using a method called, discoloration, this leaves high contrast marks on the surface without disrupting it. Additionally, the laser heats the material causing oxidation under its surface hence turning it black and this creates whatever is desired by the user.
Types Of Laser Marking Machines
There are 2 main types of laser machines available in the market. However, there is a main difference between the two of them in terms of the laser source they use. Here we will discuss the fiber lasers and the CO2 lasers.
• Fiber lasers; this laser belong to the solid state laser group. They generate a laser beam through a seed laser and amplify it in a specially manufactured glass, which is fuelled with energy via pump diodes. Fiber laser produces a small center diameter marking them powerful than the CO2 laser. Examples of fiber lasers include Vereo fiber laser, Zetalase fiber laser, and MLMe laser machine.
• CO2 laser; this are gas lasers that are based on a carbon dioxide gas mixture which is stimulated electrically. They are the most used laser types because of their efficiency and produce a very good beam quality. Minilase laser marking machine is an example of a CO2 laser machine.
Whether you want to create a permanent mark on wood, leather, stones or coated metals you can easily shop around and get high-quality laser marking machine that will get the job done. Read more about laser marking machines come visit us at Needham-Laser.com.
