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