BATCH VARIATIONS AND THEIR EFFECTS ON THE ELASTOMER-PROCESSING ILLUSTRATED ON THE MODEL OF THE INJECTION MOULDING PROCESS

For elastomeric materials the part moulding process and therewith the part properties are influenced by the production conditions during the mixing period to a major extent. Based on an analysis of the whole process chain, the influence of batch fluctuations in rubber injection moulding is discussed and the information value of different material testing procedures is evaluated regarding the further processing. Furthermore, details of the potential of artificial neural networks (ANN) and regression analysis are given by establishing an overall process correlation between the individual process parameters and the properties of compound and part.
