Fiber laser marking and engraving
Laser Marking in its technical sense means localized thermal heating achieved through the use of an amplified light beam that changes the colour of a surface to which it is directed.
Laser marking process is one of the most versatile and flexible of all industrial processes. The blackening of a product creates an indelible mark that makes laser marking a great way to identify and distinguish the product.
This technology is perfectly capable of being used in place of less effective and non-lasting techniques (screen printing, pad printing, hot stamping), as well as systems that may make unwanted incisions on details, such as micro-percussion marking or punching.
Laser marking also permits the targeted removal of paint and plating from metals and polymers.
Laser Engraving makes it possible to perform superficial and deep incisions, surface texturing, engraving on moulds and punches, and 3D-engraving also lets you place trademarks, logos or other technical or traceability information on the product itself (e.g. manufacturing date , barcode, QR Code).
By changing the setup in terms of power, frequency, or focus, the beam can become a decorative tool that can change the colour of the metal (black, red, blue, yellow, green) of the engraving area.
All laser technology techniques can be combined and used together.
Additional advantages provided by our laser technology are:
- greatest working versatility and flexibility thanks to a laser source with a Galvo head which, by installing a dynamic Z-axis, is able to work in 3 dimensions;
- extremely high definition and accurate writing, due to the small size of the writing spot of the beam (a few hundredths of a millimeter) controlled by a CNC machine;
- laser marking’s perfectly neat writing provides extremely good legibility;
- the Galvo scan head (mirrors) makes writing extremely quick;
- consistent quality and repeatability are possible thanks to completely computerized process;
- a very wide range of materials may be processed, regardless of chemical composition, hardness, shape and colour;
- the surface not affected by the light beam is left completely intact as there is no contact between the piece and the marking system. This offers makes it possible to mark otherwise not easily accessible areas;
- surfaces are physically changed, providing resistance to wear, heat and acid. Laser writing is permanent and can only be undone by complete removal from the surface;
- the system has no substantial environmental impact and is extremely eco-friendly.
