Fully Automatic 4-Cavity PET Blow Molding Machine: High-Efficiency Solution for Medium-Volume Production
YUshun Machinery proudly presents our Fully Automatic 4-Cavity PET Blow Molding Machine—a precision-engineered system designed specifically for manufacturers requiring reliable, high-output bottle production at medium volumes. This 4-cavity machine represents the perfect balance between productivity and operational flexibility, delivering production speeds of 4,000 to 6,000 bottles per hour for containers ranging from 0.1L to 2L . Ideal for beverage companies, food packaging operations, and contract manufacturers, our machine combines robust construction with advanced technology to deliver exceptional value and performance.
Key Features
1. High-Output 4-Cavity Design
Our four-cavity configuration significantly boosts production efficiency:
Simultaneous molding of four bottles per cycle maximizes throughput
Theoretical output of 4,000-6,000 bottles/hour for 500ml-2L containers
Flexible production capable of handling various bottle shapes including water bottles, carbonated soft drink bottles, edible oil containers, and cosmetic packaging
2. Advanced Servo-Driven Control System
At the core of our machine is a state-of-the-art servo control system:
Servo motor-controlled stretching rods enable multi-stage stretching for optimal material distribution
Segmented stretching capability first ensures preform verticality during positioning, then performs secondary stretching for consistent material distribution across all bottles
High positioning accuracy ensures consistent bottle quality across all four cavities
Fast stretching speed without compromising precision
3. High-Efficiency Infrared Heating Technology
Uniform preform heating is critical for consistent bottle quality:
Infrared lamp heating system with 32 lamps providing powerful, penetrating heat
Preform rotation during heating ensures even temperature distribution for optimal material stretching
Adjustable heating zones accommodate different preform structures and sizes
Automatic temperature control maintains consistent heating performance
