1. Stable and precise stretching performance During the pre-blowing stage, the stretch rod enters the preform and performs a controlled vertical stretching motion. This stable operation helps ensure even force distribution and reduces the risk of deformation.
2. Improved material distribution Working together with high-pressure air, the stretch rod helps distribute PET material more evenly inside the mold. This minimizes issues such as uneven wall thickness, off-center bottoms, or deformation at the neck.
3. Suitable for complex bottle designs For bottles with special shapes—such as contoured or shouldered designs—the stretch rod guides the material to follow the mold profile more accurately, resulting in cleaner outlines and better detail definition.
4. Enhanced mechanical properties The stretching process aligns the molecular structure of the material, improving tensile strength, impact resistance, and pressure resistance. This makes the finished bottles more durable during filling, transportation, and storage.
5. Durable for high-speed production Made from high-quality stainless steel, the rod offers good wear resistance and fatigue strength, making it suitable for continuous high-speed production while maintaining a long service life.
