Industrial marking is a system used for the unique identification of industrial products and components. Its main function is to ensure their traceability throughout production and logistics processes, a key requirement for compliance with ISO quality standards.
Laser marking is widely used across many industrial sectors and can be applied to a broad range of materials.
For this reason, it is commonly used for marking metals, plastics and even wood. Typical materials include steel, stainless steel, bronze, copper, gold, titanium, aluminium, iron, platinum, polyamide, polycarbonate, ABS, PMMA, and many others.
The main advantages of industrial laser marking include:
- No inks, masks, solvents or acids are required.
Furthermore, this technique requires no tools to come into contact with the surface being marked. As a result, the impact on the component is minimal, eliminating the risk of abrasion or smudging.
- The resulting marking is highly effective and resistant to acids, corrosion and atmospheric agents, ensuring excellent long-term durability.
The result is also extremely clean and precise, providing a very high-resolution finish. - Environmental impact is minimized, as this technique is fully eco-friendly.
- Process speed: laser marking is as fast as it is precise.
Laser marking is based on the use of laser light.
More specifically, an intense laser beam is focused onto the surface of a component. By directing this focal point across the surface using moving mirrors or a plotter head, the laser beam can create a specific image, code or text.
Depending on the characteristics of the laser source, a peak instantaneous power density of several hundred kilowatts is delivered to the target, causing an immediate modification of the surface, such as discoloration, texturing, engraving or material removal.
The way in which the material is modified essentially depends on the laser wavelength, pulse duration and the energy density of the laser beam at the focal point.
