In the DFG collaborative research centre 1120 „precision melt engineering“, the subproject B3 „self-optimizing process control strategies for a highly segmented mould tempering in injection moulding“, aims to control shrinkage and minimize warpage. The local mould temperature is controlled with the aim to homogenize the specific volume of the part during production. Therefore, a mould with 18 individual tempering zones was developed, each equipped with heating ceramics and liquid CO2 expansion chambers. Additional infrared temperature and pressure sensors allow the real-time measurement of both process parameters. This is crucial to precisely monitor and control the temperature for the tempering zones. In order to overcome dead-times resulting from the high thermal mass of the mould, a model-predictive control approach (MPC) based on the one dimensional heat transfer equation is implemented to control the tempering zones.
