Abstract
A manufacturing apparatus for manufacturing a resin container includes an injection molding part configured to injection-mold a preform, and a temperature adjustment part configured to adjust a temperature of the preform molded in the injection molding part, in which the manufacturing apparatus is configured to blow-mold the preform whose temperature has been adjusted in the temperature adjustment part, the preform is inserted into the temperature adjustment part in a state where an outer surface temperature of the preform is higher than a glass transition temperature of the preform by 30° C. or higher and 60° C. or lower, and the preform is cooled to a predetermined temperature suitable for blow molding in the temperature adjustment part.
Claims6
A manufacturing apparatus for manufacturing a resin container, the manufacturing apparatus comprising:
- an injection molding part configured to injection-mold a preform;
- and
- a temperature adjustment part configured to adjust a temperature of the preform molded in the injection molding part,
- wherein the manufacturing apparatus is configured to blow-mold the preform whose temperature has been adjusted in the temperature adjustment part,
- wherein the injection molding part includes an injection core mold and an injection cavity mold, and both the injection core mold and the injection cavity mold include a flow path connected to a chiller in which coolant is configured to flow to cool the preform such that the preform is inserted into the temperature adjustment part in a state where an outer surface temperature of the preform is higher than a glass transition temperature of the preform by 30° C. or higher and 60° C. or lower,
- wherein the preform is cooled to a predetermined temperature suitable for blow molding in the temperature adjustment part.
A manufacturing method for manufacturing a resin container, the manufacturing method comprising:
- injection-molding a preform;
- adjusting a temperature of the preform to which the injection-molding has been performed in a temperature adjustment part;
- and
- blow-molding the preform whose temperature has been adjusted,
- wherein the preform is inserted into the temperature adjustment part in a state where an outer surface temperature of the preform is higher than a glass transition temperature of the preform by 30° C. or higher and 60° C. or lower;
- and
- wherein the preform is cooled to a predetermined temperature suitable for blow molding in the temperature adjustment part.
