Laser-induced transfer of PVD-films

Transcription

1 Laser-induced transfer of PVD-films Laser Transfer ARA-LT and ARA Authentic-LT PVD films are applied directly from the carrier foil to the product surface by using a laser beam. The ARA-LT and ARA Authentic-LT technology give you the opportunity to put your logo, brand name, QR-code or other features in many different colors on a big range of different materials: adhesion- and scratch resistant, fast, flexible, low cost and Without damaging of the product surface Foto: PVD-coated foil 1

4 Laser-induced transfer of PVD-films: Examples ARA-LT : - Transfer of metals or alloys (gold, silver, steel, ) for decorative and functional puposes. - Transfer of functional color coatings on a lot of different materials and product surfaces. metal, textiles, ceramic, plastic... 4

5 Laser-induced transfer of PVD films: Characteristics and USP s ARA-LT : - The product surface itself is not or not significantly affected by the laser coating. - ARA-LT and ARA Authentic-LT are additive methods, i.e. no surface material is removed or changed in contrast to standard laser-markings. - Neither the product geometry nor its dimensions are affected. - Both technologies can be customized, i.e. customer- oder product-specific requirements can be integrated. - The ARA-LT as well as the ARA Authentic-LT technology can be implemented into the production lines at the customers site. - The laser coating technology is very cost efficient - The materials used in these laser transfer technologies are completely environmentally friendly and save resources because only a very low quantity of material is used for the laser transferable coatings. 5

6 Laser-induced transfer of PVD films: Characteristics and USP s ARA-LT : - Only PVD films are used for the laser transfer that means, no laquers or pigments are involved. - The contrast of markings is much larger compared to any conventional printing process. - The materials of the laser transfer coatings are selected with regard to the requested functional and optical features for the product. There is a big variety of usable materials for the laser transferrable coatings e,g, metals, alloys, semiconductors as well as insulators (ceramic hard coatings) and combinations of them. - The ARA LT color layers are generated during the PVD process and just transferred then or they are finally determined by the appropriate laser parameter settings. - It is also possible to transfer metal layers, e.g. gold, silver, copper, titanium, aluminum, zirconium, etc. without changing their material properties. 6

7 Laser-induced transfer of PVD films: Characteristics and USP s ARA Authentic-LT : Forgery-proof laser coatings - Specific and significant color effects - easy visible with the bare eye. - Fast, simple and reliable verification of originality is possible and can be proceed by using our App s, available for standard smartphone. - Forensic proof is done with a VIS/NIR spectrometer. - The proof of originality can be combined with identification features (Data-Matrices, Barcodes, ). - The forgery-proof laser coatings can be integrated into an existing corporate identity - The Ara Authentic-LT technology can be applied for low costs on products and are also suitable for the implementation in mass production - directly at manufacturers site.
