This paper describes a numerical model for predicting temperature fields both in the glass and the mould tools during cyclic glass pressing processes. The model uses the TLM (transmission line modelling) technique and relevant aspects of the technique are described. The model is used to predict the effect of changing various parameters on the steady state temperatures developed.
