Abstract
A stretch blow molding system that condition preforms such that the temperature distribution within the cross-section of each preform is optimized prior to blow molding operations is provided. The system has a temperature measurement and control system capable of directly monitoring both the outside as well as inside surface temperature of preforms at different stages of transport throughout the thermal conditioning section of the system.
