<p>The present invention relates to manufacture of container product with a constant level of quality, wherein the performance is constant, by resolving problems including transformation of perform performance caused by the temperature variation of the preform; or by the variation in the stretching blow molding due to a thermal difference between the surface and the inner part of the preform, resulting from the thickness thereof, in order to industrialize a new molding method recognized to be an excellent molding method from the point of view of economic efficiency and production efficiency, wherein compression molding and stretch blow molding are performed continuously. By a method or device for manufacturing continuously synthetic resin containers, preforms are molded by compression with a compression molding machine, then stretch blow molding is performed with a stretch blow molding machine. After discharging molded preforms from the compression molding machine, an even-heating treatment of preforms, a partial heating or partial cooling treatment according to need and then stretch blow molding are performed.</p> |
