A program for calculating the temperature increase in rubber compounds during the injection phase was created and verified in experiments in course of the FFG-Bridge research project “Cure time reduction” at the Montanuniversität Leoben. Another tool helps the user to evaluate the potential cure time reduction at an early stage before process optimization. In a software-supported cure time reduction while securing the complete curing of the molded parts a significant cycle time reduction and minimized energy consumption can be achieved. The second objective of the project was to analyze the potential for cure time reduction using coupled shear and elongational heat generation in conical dies and predict this effect by means of the previously mentioned calculation program. Furthermore, the compression heating in rubber compounds was scientifically investigated for the first time.
