Abstract
To obtain simultaneous filling of all cavities (K1-K4) in multicavity injection moulds, the mould cavity pressure (p) patterns in all cavities (K1-K4) are detected and the times (t1-t4) measured from the beginning of filling till a suitably chosen reference pressure (pR) is reached for each cavity (K1-K4). By interventions in the individual heating systems of the individual hot runners (5), the temperatures in these are altered to bring the measured times of the individual cavities more in line.
