Blow Molding Process
Heating and Shaping
The blow molding process begins with the preparation of raw plastic. Workers blend the material with colors and additives to achieve the desired properties. The plastic then moves into the extrusion stage, where machines heat it until it becomes molten. This molten plastic forms a parison, a hollow tube that will become the final bottle. The parison enters a mold, where high-pressure air inflates it to match the mold’s shape. The bottle blowing process relies on precise temperature control and advanced technology to ensure quality.
| Factor | Description |
|---|---|
| Mold Temperature | Controlled at 120℃~145℃ to eliminate internal stress and improve crystallinity for high-temperature resistance. |
| Heating Method | Utilizes far infrared radiation and heat circulation for uniform heating of the bottle preform. |
| Cooling Process | High-pressure cooling air shapes the bottle wall after blowing, ensuring structural integrity. |
Proper heating and shaping guarantee that bottles have strong walls and consistent quality. The cooling process locks the shape and prevents defects, making the blow molding process reliable for beverage packaging.
Automation and Industry 4.0
Automation plays a key role in the blow molding process. Custom conveyors transport preforms to the heating machine, ensuring safe and efficient movement.
