A core rod assembly (10) for blow molding includes a core rod head (16), a first fluid pathway (A1) extending along a first length of the core rod head (16), and a second fluid pathway (A2) extending along a second length of the core rod head (16). The first and second fluid pathways (A1, A2) may be fluidly isolated from each other and provide selective temperature control of respective first and second portions of the core rod assembly (10) during the blow molding process. At least a portion of the first fluid pathway (A1) may be longitudinally offset from the second fluid pathway (A2) so as to define respective first and second temperature zones (zone 1, zone 2) along the respective first and second portions of the core rod assembly (10).

A process for regulating a cyclical production of containers by stretch blow molding from preforms, comprising an initializing phase, a regulated production phase, and a stabilizing phase. In the regulated production phase, the preblowing curve is measured and stored, and a real instant and/or a real pressure is calculated, corresponding to a characteristic point. A new value of at least one operating parameter of the machine is calculated as a function of a difference between a real instant and a reference instant and/or between a real pressure and a reference pressure. The regulated production phase monitors for change, imposed by the operator, of a value of an operating parameter of the machine and automatically updates the regulating parameters in the stabilizing phase while production is continued. The process also corrects the reference instant and/or the reference pressure as a function of the real pressure and/or real instant values stored.
