Abstract
A method of vulcanizing an elastomer product such as a tire including placing the product in a mould, supplying a heating medium to the interior of the product to effect vulcanization, then supplying a pressurizing medium to the interior of the product. In this method the heating medium or the heated fluid mixture is exhausted or removed from the interior of the product at least once by opening an exhaust and simultaneously supplying a cooling pressurizing medium to cool the product to a required temperature level. The heating medium may be exhausted immediately after the completion of the heating medium supply process. The heated fluid mixture may be exhausted in and/or after the pressurizing medium supply process. Preferably the rate of exhaustion is limited by a control orifice. As a result the product is cooled without giving temperature differences in different parts of the product and avoiding unfavorable pressure drop so that efficient vulcanization with good homogeneity in the product results.
