Today, several complex process steps are necessary to create plastics parts with functional surfaces. The Institute of Plastics Processing (IKV) at RWTH Aachen University developed a new process technology that allows the manufacturing of superhydrophobic surfaces directly in one single step. By means of a special variothermal process control in the injection molding process, microstructures are replicated precisely and afterwards stretched out during the demolding process. This leads to the creation of a unique, highly functional hair like surface topography.
The combination of moulding and surface functionalisation in a process suitable for mass production allows the manufacturing of sophisticated products in a shortened process chain.
