Abstract: The present disclosure includes a thread insert for a blow mold assembly configured to form a polymeric container. The thread insert includes: an inner mold surface defining threads, the inner mold surface configured to form a finish of the container; a first bore defined by the thread insert; and a first heating element seated within the first bore and configured to heat the inner mold surface.

Abstract: A method for forming a preform or part including the following: dispensing an initial amount of an additive and a thermoplastic resin into an injection molding machine; forming the preform or part by operating a molding machine to inject the thermoplastic resin and the additive at the initial amount into a mold of the preform or part; measuring realized visual parameters of the preform or part; comparing the realized visual parameters to the target visual parameters and determining whether the realized visual parameters are within a predetermined acceptable range of the target visual parameters; if the realized visual parameters are outside the predetermined acceptable range of the target visual parameters, adjusting the initial amount of the additive to a modified amount estimated to achieve the target visual parameters; and forming an additional preform or part by operating the injection molding machine to inject the thermoplastic resin and the additive at the modified amount into the mold of the preform or

Abstract: A device for blow molding a container from a preform. The device includes a mold base and a pedestal for supporting the mold base. An electric heating element is beneath the mold base for heating the mold base. An insulator is between the heating element and the pedestal.

Abstract: A blow mold assembly for forming a polymeric container. The blow mold assembly has a thread insert defining threads configured to form finish threads on a finish of the polymeric container. An electric heater of the blow mold assembly is configured to heat the thread insert as the polymeric container is formed.
