Abstract
Surface topography is of great importance in polymer micro fluidics, therefore the replication capability of the process and the surface quality of the tool has to be suitably optimized. In this paper, optical profilometry (white light interferometry, WLI) is implemented for topographical characterization of polymer surfaces. In particular the study considers replication performance of injection moulding applied for the realization of microfluidic systems for blood analysis.
Parts were produced by means of a series of statistically designed injection moulding experiments. Three process parameters have been controlled: temperature of the melt, temperature of the mould and injection speed. Hybrid tooling was employed for the tool making process and two different types of surfaces were obtained within the micro cavity: a finely finished flat surface (average roughness Ra
