Equipped with a high-performance high pressure air supply system with a pressure specification of 35Kg/cm², the machine ensures uniform and powerful blowing force. This feature guarantees that PET preforms are fully expanded into bottles with consistent wall thickness, enhancing product durability and leak-proof performance.
Adopting the "one mold for one size of bottle" principle, the machine supports customized PET bottle moulds for different capacities and shapes. This precision matching not only ensures accurate bottle dimensions but also simplifies mold replacement, improving production flexibility for multi-sku operations.
The integrated preform heating module features uniform temperature distribution, effectively softening PET preforms to meet blowing requirements. This reduces preform waste and shortens production cycles, boosting overall production efficiency by up to 30% compared to conventional machines.
Combined with a water cooling tower and chiller, the machine’s cooling system rapidly cools finished bottles and moulds. This accelerates bottle shaping, prevents deformation, and maintains stable production continuity, even during long-hour operations.
The machine adopts an intuitive control interface, enabling operators to easily adjust parameters such as heating temperature, blowing pressure, and production speed. Minimal training is required, reducing labor costs and operational errors.
