<p>A method and a device for continuously manufacturing a synthetic resin container by compression-molding a preform by a compression-molding machine and continuously stretch blow- molding by a stretch blow-molding machine. In the continuous molding method, to industrialize the molding method for continuously performing compression molding and stretch blow molding which is recognized as an excellent molding method from the view points of economic efficiency and production efficiency, problems such as the deterioration of preform performance due to a change in temperature of the preform or a variation in stretch blow molding properties due to a difference in temperature between the surface and inner part of the preform resulting from the thickness of the preform are solved to manufacture product containers with constant performance and excellent quality. After the molded preform is taken out from the compression molding machine, soaking treatment is applied to the preform and, as necessary, partial heating or partial cooling treatment is applied thereto, and then the stretch blow molding is performed for the preform.</p> |
