Characterisation of demoulding parameters in micro-injection moulding [PDF]
Microsystem Technologies, 2014 Condition monitoring of micro injection moulding is an effective way of understanding the processing effects of variable parameter settings. This paper reports an experimental study that investigates the characteristics of the demoulding behaviour in micro injection moulding (µ-IM) with a focus on the process factors that affect parts' quality. Using a
