Laser marking: features

Indelible encoding and high quality graphics; total reliability and Non Stop productivity. No consumables, no residues. Light doesn’t pollute!

The term LASER is the acronym for Light Amplification by Stimulated Emission of Radiation: a source of electromagnetic radiation that amplifies a monochromatic, coherent (unidirectional) and concentrated light source with high power density.
Laser marking Is a “contact free print” technology that offers a range of undeniable benefits compared to alternative processes

Lasers provide the most advanced marking and encoding system, a process that is both efficient and effective. An investment with a certain return that is easily quantifiable

There are many different types of laser marking machines that are used to engrave, etch or mark, and cut a wide range of materials in many different industries. At the heart of each laser machine, there is a laser source: the most common are CO and fiber laser markers.

CO laser is a gas laser based on a gas mixture of carbon dioxide stimulated electrically with a 10.6 micrometers wavelength. They are particularly suitable for etching organic materials and marking plastics.

Fiber Laser produces the laser beam by a laser seed amplified through glass fibers fed with energy by pump diodes. With a wavelength of 1.064 micrometres, fiber lasers produce a particularly small focal diameter, their intensity is up to 100 times higher than that of CO₂ lasers but with the same average power emitted. The fiber laser is particularly suitable for marking metals, engravings on metals and markings particularly rich in plastic contrasts. Laser fibers are maintenance-free and stand out for their long life.

A special type of laser fiber is the MOPA laser in which the pulse duration is adjustable. This makes the MOPA laser one of the most flexible lasers ever, which can be used in many applications including color marking on steel.
They are suitable for these materials: metals, coated metals, plastics.
