20230118659 · 2023-04-20 ·

When a preform having been molded while released from a mold at an earlier timing in an injection stretch blow molding machine is stretched and blow molded, the bottom of the preform is prevented from rupturing and the bottom of a hollow molded article is prevented from being uneven in wall thickness to produce such a hollow molded article without defect bottom by the injection stretch blow molding machine. An injection molding process of injection molding a preform; and a blow molding process of blow molding the preform to obtain a hollow molded article. The blow molding process allows a tip of a stretching rod cooled to a temperature between 50° C. and 90° C. to be brought into contact with the bottom of the preform in a softened state, and to press down the bottom of the preform while the bottom is cooled.

VARIABLE COOLING DURING BLOW MOLDING PROCESS
20230158730 · 2023-05-25 ·

Provided is a method for producing thermoplastic articles. The method comprises forming a hollow parison of heated thermoplastic material and positioning the parison within a cavity of a mold tool, the cavity defining the external configuration of the desired article. Fluid pressure is then applied to an internal chamber defined by the parison upon closure of the mold tool, to expand the parison to conform to the mold cavity. The formed article is then subjected to an in-mold cooling phase to reduce the thermal energy of the formed article sufficiently to permit for safe ejection with reduced distortion. The cooling phase is defined by a variable cooling protocol that applies one or more cycles of thermal shock to the formed article during the in-mold cooling phase.
