A new way to administer painless medication is to use plasters with microneedles. However, the production of this plaster is not yet perfected. Sirris and KU Leuven have investigated whether an injection moulding process could be used to produce these needles in large quantities and at a very low ...

Sometimes the question arises to what extent cryogenic cooling is environmentally-friendly, as the gases used are a consumable, unlike other refrigerants that can be reused. Cryogenic processing does have interesting environmental advantages. The environmental impact of the entire cryogenic cooling ...

Cryogenic cooling during machining stands for machining at very low temperatures. This has advantages both for tools made of heat-resistant materials, where the heat can be high during machining, and for the machining of softer materials, which will flow more easily during machining.

Almost 10 years after the introduction of cryogenic machining, a lot of research has been conducted on this technology, its application and pros and cons. However, despite the positive results, the step to the industry does not seem to be so obvious. High time to present this interesting machining ...

Solid carbide endmills are the most commonly used tools in almost every machine shop. Process engineers are always concerned with productivity gains by reducing the tooling cost, machining time and bring down the cost per part to increase the margins. The selection of the machining conditions either ...

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.

How effective you can machine a part largely depends on the structural dynamics of all the components involved in the process. It can be seen as two systems: one concerning the machine tool, which includes the drives in the spindle, the tool holder and the cutting tool, while the other system ...

Structures are already widely used to give functionality to a surface, with nature as the best example. However, in order to use this in technical applications, we must take into account the limitations and possibilities offered by the various (current) production methods.

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.
