The most unique features of laser marking are that it can achieve automation, high-speed processing, and complicated patterns while leaving permanent marks on a wide range of materials. If you are not clear with the working principles of a laser marking machine, such extraordinary functions may seem to be unbelievable for you. So, please let me tell you more about this magical process of how it works.
Here is the content list:
l What is a laser?
l How do laser marking machines work?
An amazing fact you may not know is that the term "laser" is actually an acronym for "Light Amplification by the Stimulated Emission of Radiation". The production of laser could be listed as follows: The laser beam starts with atoms that are excited to release light particles. This light can be concentrated and directed towards the laser marking area. Such concentration of light and energy can easily mark, cut, and melt various kinds of materials. The energy released is measured in wavelength or nanometers (NM). The higher the wavelength, the stronger the laser beam. For example, a UV laser marker with a wavelength of about 355NM can provide lower power for marking heat-sensitive materials such as plastic and glass. Since UV laser markers and other machines in the "cold laser" category emit less energy, they are an ideal solution for many organic or soft products because they are less likely to burn materials. On the other hand, the operating frequency of the fiber laser is 1070NM, which can provide higher power to mark harder materials, such as metals.
After knowing what a laser is and are the differences between different kinds of lasers, now we can focus on getting deeper knowledge about how laser marking machines work. Generally speaking, a laser marking machine is performed by using a focused beam to mark the surface of the material. The types of laser could be fiber, pulsed, continuous wave, green or UV lasers. When the light beam interacts with the surface of the material, it changes the properties and appearance of the material. This concentrated beam is aimed only at a specific area, so that the laser marking machine can create accurate, high-quality, high-contrast marks that can be read or scanned on almost any surface, and keep the safety of its working process at the same time. This feature not only makes laser marking ideal for applications where accuracy and permanence are critical to success but also makes it suitable for a great variety of working places and applications since the exact process area of laser marking machines is only a small area of the surface of workpieces. That is all about the working principles of laser marking machines.
