Friction between moving parts plays an important role in many applications. The lower the friction, the less energy is needed to move parts and the less wear and tear will occur. Research at Sirris has shown that applying small holes in sliding surfaces has a positive effect on friction behaviour.

What is the role of surface functionalities and, in particular, the role of textures, in the manufacturing industry in Belgium? That is the question we asked our member companies last summer with a view to rolling out a service on surface textures. The (concise) results are presented in this article.

Looking for a technology for creating very small structures? The laser pulse duration with femtosecond laser technology is so short that the material does not have the time to heat up and immediately evaporate, so that protruding edges do not arise.

The potential of lasers has become huge thanks to recent technological developments, thereby also increasing the potential of surface functionalisation by means of laser texturing. New functionalities and possibilities become available to the industry and Sirris will investigate these for you.

Thanks to the latest technological advances lasers can perhaps in the future be used in the fight against copying by providing products with a texture.

Using laser technology for marking is growing rapidly. Various suppliers of laser marking equipment are presenting what they have to offer at the EMO trade fair in Hanover in Germany.

During the PLI conference in Colmar on 25 and 26 September, the latest results from the laser community for scaling up the femtosecond laser were presented.

It is possible to make the Printed Circuit Boards (PCB) thinner using a femtosecond laser.

LED lighting has the advantage of being small and providing a lot of light for lower energy consumption. A challenge is to keep the temperature of the LED low.

LED light is on the rise. This is because of the high efficiency, low energy consumption. One of the challenges is shaping the light beam according to customer needs with a minimum of lens material. We are investigating this aspect in collaboration with KU Leuven in the context of the ‘Lighting industry 4.0’ project.
