1-Cavity High-Speed Forming with 700BPH Stable Output
The HQ-20L adopts a 1-cavity forming structure optimized for 20L large-capacity bottles, achieving a stable output of 700 bottles per hour—consistent with the advanced level of similar 1-cavity models in the industry. The independent cavity design avoids mutual interference during forming, ensuring uniform wall thickness and high qualification rate (over 99%), suitable for mass production of large-capacity packaging.
Variable-Pitch Transmission for Smooth Operation
The main components of the HQ-20L feature a variable-pitch transmission design, which optimizes the conveying speed and forming rhythm of the preform. This design not only improves forming efficiency but also reduces energy consumption and component wear, enabling 24-hour continuous stable operation with a low failure rate—effectively reducing production downtime.
20L Large-Capacity Special Design
Customized for 20L large-capacity bottles, the machine supports a maximum bottle diameter of 300mm and height of 500mm, perfectly adapting to the production of oil bottles, chemical reagent bottles and bulk packaging containers. The optimized mold clamping structure ensures sufficient clamping force for thick-walled large-capacity bottles, avoiding leakage and deformation.
Precise Heating System for High Forming Quality
Equipped with 4 heating ovens and 48 high-efficiency lamp tubes, the HQ-20L ensures uniform and sufficient heating of preforms. The 42 heating heads adapt to the heating needs of large-capacity preforms, improving the forming precision and surface smoothness of finished bottles—meeting the strict quality requirements of industrial packaging.
Technical Parameters of 20L Fully Automatic Bottle Blowing Machine
With 20L large-capacity compatibility and stable forming performance, the HQ-20L is widely used in edible oil, chemical, bulk packaging and other industries. It can produce food-grade, chemical-resistant large-capacity bottles, meeting the packaging needs of high-volume, heavy-duty products.
All core components of the 20L fully automatic bottle blowing machine are made of high-strength materials, ensuring long service life and stable operation under continuous production conditions.
