2. Working Principle of the One-Step Molding Process
The operational mastery of an advanced injection stretch blow moulding machine is defined by its seamless three-station or four-station rotary mechanism, which meticulously transforms raw thermoplastic materials into flawlessly finished containers. At the very first station, the injection molding phase takes place, where raw resin pellets are thoroughly melted and precisely injected into an injection stretch blow mold cavity surrounding a core rod. This crucial step dictates the initial wall thickness and material distribution of the preform. Without releasing the preform, the rotary table seamlessly transfers it to the second station, dedicated to temperature conditioning and tail cutting. Here, the preform is subjected to an optimized, differential heating profile—ensuring the body remains perfectly malleable while the threaded neck is kept cool and rigid—and a servo-driven cutter removes the injection gate tail. Following this, the preform enters the third station for the actual stretch blow molding phase. A mechanical stretch rod extends downwards to axially elongate the preform, while simultaneously, high-pressure air is blasted through the core, expanding the material radially against the chilled walls. Finally, at the fourth station, the finished container is sufficiently cooled, ejected from the core rod, and smoothly transferred to the downstream packaging line, culminating a highly automated cycle often showcased in an impressive injection stretch blow molding video that takes mere seconds to complete.
