While the shear stress and the initial temperature input reduce the viscosity, the crosslinking reaction starts after the incubation time at a certain temperature, which abruptly increases the viscosity. The viscosity of LSR is influenced by several overlapping factors during processing. If it is too high, the LSR cannot lay into the nano- and microstructures and the structures will not be completely imprinted. The viscosity of the LSR plays a decisive role. To ensure process-reliable molding of the microstructures, the influence of various process settings on moldability is investigated in this work. For example, antibacterial, self-cleaning or tribologically and haptically optimized surfaces can be produced directly during injection molding. The functionalization of surfaces through nano- or microstructures introduced directly in the injection mold opens up new fields of application. The reasons for this are its outstanding properties and economic processability. The processing of liquid silicone rubber (LSR) in the injection molding process is becoming increasingly important.
