Abstract

Micro-injection moulding is becoming increasingly important among the available proc-esses for production of micro-electromechanical systems (MEMS) and microsystem tech-nologies (MSTs), and higher number of polymer products is being manufactured by thisprocess. Due to the sensitive nature of applications of this process, such as medical andaerospace applications, achieving high quality parts with high dimensional accuracy iscrucial. In this work, a design of experiment (DoE) approach is used. The aim is to studythe effects of three process parameters which are commonly used for research in this do-main, on the dimensional accuracy of microchannels with different sizes; they are injec-tion velocity, injection pressure, and melt temperature. The study focuses on twopolymers, polyoxymethylene (POM) and liquid crystal polymer (LCP). Experimentalresults showed that higher melt temperature and injection pressure resulted in higherdimensional accuracy. Nevertheless, high settings for the three parameters resulted inhigher percentage of flash in most cases. In conclusion, the most influential factors wereshown to be melt temperature and injection pressure.
