Publication number: 20230211925Abstract: A method of injection molding a test tube-shaped preform for biaxial stretch blow molding includes supplying a major material resin from outer and inner flow paths to a combined flow path for a predetermined time and rate. For a period of time within a range of the predetermined time period during which the major material resin is supplied, the intermediate layer resin is simultaneously supplied from the middle flow path to the combined flow path at a second predetermined supplying rate. A columnar laminated molten resin is injected into a cavity of a metal mold connected to a tip of the nozzle through a gate to fill the cavity, the columnar laminated molten resin being composed of the major material resin and the intermediate layer resin formed in the major material resin in a laminated manner that are combined into a columnar shape at the combined flow path.Type: ApplicationFiled: February 27, 2023Publication date: July 6, 2023Applicant: YOSHINO KOGYOSHO CO., LTD.Inventors: Hiroshi HOSOKOSHIYAMA, Junichi CHIBA, Seiji ISO
