ABSTRACT:
The invention relates to a method for vulcanizing an elastomer, such as tire, fender, sleeve, hose, etc., set in a vulcanizing chamber by use of a mixed fluid comprising a low enthalpy gas and a high thermal capacity thermal fluid, said mixed fluid being obtained by introducing said gas and fluid each independently into the vulcanizing chamber for direct mixing in said vulcanizing chamber, the temperature, pressure and flow rate necessitated for the vulcanization of the vulcanizable elastomer being adapted to be controlled by a temperature sensor and a pressure sensor provided inside the vulcanizing chamber thereby making it possible to obtain proper vulcanization without the conventional impediments of surface bareness or imperfect adhesion in the part of the carcass due to insufficient exhaust in air.
