Assisted injection moulding-based technologies will be developed, as they are the perfect candidates to achieve cost-efficient production of highly reproducible and highly reliable 3D plastic parts with functional micro- and nanostructured surfaces.
The filling of micro- and nanostructured moulds requires the optimal control of the polymer flow during the injection process. This will be achieved, notably by implementing peripheral technologies like rapid heating & cooling (e.g. using pressurized water-based system involving optimized cooling channels in mould made with Selective Laser Melting of metal powder, inductive heating, etc.) and vacuum technologies.
The optimal filling of the micro- and nanostructured moulds is not sufficient to ensure the quality of the final polymer parts. The replicated micron and sub-micron structures can be irreversibly damaged during the demoulding step, especially on 3D parts. Innovative solutions of assisted demoulding based on ultrasonic technologies are proposed in this project.
