ABSTRACT:
Finite element analysis or thermocouple probes are used to determine the state of cure for each zone of a non-uniform, thick rubber article, such as a large tire or a tread for a tire. From this knowledge of those cure-limiting zones, heat transfer elements are added to the mold to enhance the transfer of heat into these cure-limiting zones and to provide a more optimum cure. The use of heat transfer pins and/or mini-sipes are an efficient and practical means of reducing total cure time in the press and optimizing cure state without substantially affecting the performance of the article such as the tire. Reductions in cure time of 10% or more are demonstrated.
