Working Principle
The neck ring works together with the core and cavity during injection molding to define the final neck finish of the PET preform. It controls critical dimensions such as thread profile, sealing surface, and neck height.
BJY neck rings are engineered to maintain dimensional consistency under high injection pressure and elevated temperatures, ensuring smooth demolding and reliable downstream bottle performance.
