The manufacturing of tyres requires mastering the control of curing process which has a significant effect of the thermal and mechanical behavior of the formed part. Basically, curing analysis can be considered as thermal-mechanical coupled phenomena with heat consuming character and significant dependence of physical properties on temperature. Quite a number of papers deal with chemical aspects of rubber curing, compare numerous cure reaction kinetic models, discuss various mathematical models for the simulation of the vulcanization and demonstrate the interaction between temperature distribution fields and curing degree fields (Bafrnec, 2007). The mail goal of this paper is to focus on the understanding of the heat transfer in a cure press with respect to the used heating procedure and the designs of the cure mold. Moreover, a comparison between the effectiveness of steam dome and heating plate cure presses is made. The findings can be used for the optimization of curing cycles and thus for increasing the quality of the final product as well as for the potential energy consumption reduction.
