Abstract

The demand for micro components has increased during the last decade following the overall trend towards miniaturization. Injection moulding is the favoured technique for the mass manufacturing of micro components or larger parts with micro-structured areas due to its ability to cost effectively replicate very complex shapes, precise tolerances and in high numbers. In order to secure Europe’s leading role in the sector of micro-fabrication the capabilities of injection moulding need to be further developed.
In this research a product for telecommunication, a diplexer unit, has been manufactured utilizing the injection moulding process. A design of experiment study has been carried out, varying process parameters such as injection speed, holding pressure, mould- and barrel temperature. The replicated parts are characterized by measuring geometric features and the part weight. Using an evaluation algorithm for modelling, the influence of different moulding parameters on the final part quality was assessed. Firstly a process model and secondly a quality model has been calculated. The results shows that part quality can be controlled by monitoring characteristic numbers.
