Abstract:
PURPOSE:To form a container without unevenness in a short time by adjusting the temperature of an preform injection mold by means of an injection mold, releasing the same during the high temperature and carrying out stretch blow molding immediately. CONSTITUTION:Releasing out of an injection mold of a reform molded by injection filling molten resin in the injection mold is carried out while the shape is in the state of being able to retain by means of a skin layer formed on the surface by quenching and also in the state of high temperature because of the external cooling not being completed. The stretch blow molding of the preform is performed within the time (t) in which the surface temperature of the preform is risen by its own external temperature to the peak temperature.
