Abstract

Method and device for pressurizing the inner surface of a molded cylindrical article by the step of pressurizing and forming the inner surface of the article while rotating a pressing unit (6a) of pressurizing means (6) relative to a molded article (2) during a period of time which begins immediately after completion of solidification of the article ready for pressurizing and forming, and which continues until the transition temperature of the article has been reached the temperature at which the tensile strength and elongation of the article undergo an abrupt charge. This is performed in order to pressurize and cause the collapse of blowholes and air bubbles in the molded article, and to harden the inner surface thereof.
