Abstract
Disclosed is a method for manufacturing a container from a blank in a mold provided with a movable insert, wherein the method includes the following phases: pre-blowing; blow molding; boxing; and the following operations: measuring the prevailing pressure in the blank in real-time and storing the measurement in a memory; measuring the position of the insert in real-time and storing the measurement in a memory; detecting a time tS2 indicating the actual start of the blowing phase and moment tB2 indicating the actual start of movement of the insert and storing same in a memory; calculating T1=tS2−tB2; comparing T1 with a predetermined non-zero reference T1ref, as long as T1 is different from T1ref, and delaying the start of the boxing phase.
