1 UV-Marking Development of new laser for customization at industrial level through high quality marking on different materials Coordinated by B/S/H A collaboration between: B/S/H ROFIN SINAR LASER GMBH WIRTHWEIN AG MERCK KGAA ILVA GLASS SPA TORRECID ICMA U-MARQ LIMITED EU-Funded Project. Ref_314630
2 General Information Title: UV-Marking. Development of new laser for customization at industrial level through high quality marking on different materials Funded under: FP7_2012_NMP_ICT_FoF (Factories of the Future)_Cooperation Project reference: Total cost: 6.10 million euro EU contribution: 3,65 million euro Start date: Duration: 36 months
3 Contact details Project Leader: Mr. Andrés Escartín Mail Phone +34 (976)
4 Introduction to the project
5 Objectives Developing a new laser in the UV range Adapting existing materials for having a better beam absorption Integrating the laser in the industrial process Developing a user application for demonstrating the unitary customization with real customers
6 Project Background IR UV PP
7 Project Background CaCu 3 Ti 4 O 12 Metal Laser: Frequency of pulses, velocity, fluence (energy/area), number of runs, distance lenssample, time of pulse, wavelength Interaction laser/matter depends on: Absorption at the laser wavelength, composition, internal microstructure, mechanical properties, thermal properties, fillers
8 Interaction between light and matter depends on the wavelength Important laser parameters Pulse duration Pulse energy Velocity Beam quality Material absorption determines the degree of interaction Project Background
9 Project Background Ultraviolet Laser (UV) Green Laser (GN) Infrared Laser (IR) Effect Photo chemical ablation Photo chemical activation* Photo mechanical ablation Phototermal ablation Melting, burning and vaporization Main fields of application Engraving and ablation Engraving and ablation Engraving Tempering Coloring and foaming Materials Mainly for glass, ceramics, plastics Mainly for ceramic materials or coated materials Most materials (metals, plastics, glass, ceramics ) Features High resolution and contrast Aesthetic and colored markings possible High resolution and contrast Aesthetic markings possible Bad resolution and bad contrast Broad field of application Fast processing
10 Engraving and ablation For engraving, the laser beam removes the material. Ablation is the partial removal of coating layers from the base material. Application for most materials (metals, plastics, ceramics ) Annealing Oxidation. Black colors Annealed markings can be generated by using the laser beam to heat the work piece to a certain temperature where the marking should appear. This creates oxide layers on the surface whose composition determines the colored appearance. For ferrous metals and titanium Coloring and foaming. Chemical reaction Foaming. White marks Carbonization. Black marks Photochemical reaction. Any color For plastics only Project Background
11 f = 300 f = 254 f = 160 An electro-magnetic wave is generated by a laser-active medium (Neodym, CO2,..) The amplified beam is deflected to the marking area. The size of the marking area depends on the distance between the lens and the marking surface (the larger the focal distance, the bigger the marking area). Irradiance is very important Project Background 120 x x x 240
12 Comparison of a topographic profile of a transverse cut of samples UV and green, represented with the same scale. It appreciates that the hurt in the material is very much minor, and surface presents a more homogeneous appearance Project Background
13 Project Background Engraving decoration by ablation at the surface Advantages Stable marking process Cold engraving Durable marks No mechanical damage Very high precision (10 microns) Digital Marking Flexibility Customization Time to market Inline product differentiation Design improvement 30 microns minimum width Up to 300 dots per cm Unlimited grey tones in one sample Any shape can be marked UV Green
