What is laser marking?
In today’s rapidly developing world of industrial technologies, laser marking is an innovative method of applying permanent markings to various materials. But what does it really mean? Imagine a machine that can precisely mark any element without even touching it for a moment. This is what laser marking offers – a technology that uses a laser beam to modify the surface of the material. Importantly, this process is non-contact and extremely precise, which minimizes the risk of damaging the product. This technique is based on thermophysical or thermochemical reactions that lead to a change in color, engraving, and sometimes even removal of a fragment of the material. Thanks to this, you can obtain permanent, clear markings that are resistant to abrasion and external factors. Laser marking is widely used in industry, where it is used to identify and mark parts, making it an invaluable tool in production processes.
Laser marking definition and operating principle
How exactly does laser marking work? The process involves using an intense laser beam to modify the surface of a material by staining, engraving, or removing a section of it. The key element is a concentrated beam of light that causes a permanent change in the outer layer of the material. This works on the principle of precisely controlled thermophysical or thermochemical reactions, which allows you to achieve the desired effect.
What’s more, laser marking is incredibly versatile because it can be used on a variety of materials, such as:
METAL
PLASTIC
GLASS
WOOD
STONE SLATE
LEATHER
This versatility makes the technology not only effective, but also flexible, adapting to the specific needs of various industries.
