Method for the production of filled containers from thermally conditioned preforms
11707877 · 2023-07-25 · ·

A method for producing containers filled with liquid content from preforms made of thermoplastic material. The liquid content is fed as a pressure medium into thermally conditioned preforms during a forming and filling phase in a mold of one of a plurality of forming stations arranged circumferentially spaced apart on a common, continuously rotationally driven working wheel. A compensating device compensates for thermal consequences of centrifugal force acting on the liquid content fed into the preform during the forming and filling phase. The compensating device imparts a temperature profile to the preform in a circumferential direction, which is not point-symmetrical in relation to a longitudinal axis of the preform to produce a thermally differentiated partial circumferential region. The preform is inserted into the mold such that the thermally differentiated partial circumferential region faces in a radial direction of the working wheel.

ENERGY EFFICIENT BLOW MOLDER CONTROL

Blow molder system and associated method optimizes the performance, energy efficiency and/or operating costs of the blow molder. A blow molder controller executes a system model that relates blow molder input parameter changes to the characteristics of containers generated by the blow molder.
