摘要： A method enabling stretch blow molding in a temperature range preferable for polyethylene and capable of releasing at a surface temperature suited to both releasing of a preform and subsequent stretch blow molding, by disconnecting the core die and the preform in advance by the use of pressure of gas. The injection molding of a predetermined preform involves filling an injection mold with molten polyethylene, releasing the preform from the cavity die and core die of the injection mold while a mouth portion of the preform is held by the lip die, and transferring the preform into a blow die to stretch blow mold into a hollow molded thin wall product. Gas forcibly enters into the boundary of the core die and the preform, before releasing the preform from the injection mold to isolate the inside wall of the preform from the core die. Releasing is effected while the inside of the preform is not completely cooled and is still at high temperature, and in a temperature range in which the surface temperature of the preform right after releasing is 80 to 90 deg. C. The step of stretch blow molding is performed within the time interval before the surface temperature of the preform which is elevated by the internal heat of the preform reaches 120 deg. C.

摘要： There is provided a method of molding a large container including the steps of preparing a preform from an injection-molded, thick-wall, closed-end parison by repeatedly and intermittently applying an air blow pressure to the parison and releasing the air blow pressure therefrom, and stretch blow molding the preform to a thin-wall large container. The closed-end parison is released from a mold immediately after a skin layer, keeping a parison shape, is formed on the surface of the closed-end parison having a high inner temperature, and is then molded to a preform with a preform mold heated to a predetermined temperature, while the surface temperature of the parison is increased by the inner temperature. The preform is kept at a stretch blow molding temperature and is stretch blow molded into a blow mold to produce a large container.
