Product Description
The Fully Automatic PET Servo Blow Moulding Machine 8 Cavity is designed for high-efficiency production of PET bottles and containers for bottled water, carbonated soft drinks, juice, cleaning products, medical products, pesticides and other packaging applications.
The machine integrates preform heating, stretching, molding and bottle output into an automated production process. Its servo-driven motion system provides precise control of stretching, preform transfer and mold operations, helping maintain stable production and consistent bottle quality.
With an infrared preheating system, adjustable heating components and automatic temperature control, the PET bottle blowing machine can provide uniform heating for PET preforms before the blowing process. The four-template structure with double opening and closing action is designed to reduce mold-clamping time and improve production efficiency.
The machine supports multiple cavity configurations within the Yaoshi PET blow molding machine range. The available configuration data shows theoretical outputs up to 16,000 BPH for the 8-cavity configuration, with a maximum bottle volume of 2 L in the listed main configuration.
Features
Our water bottle making machine is designed for the production of plastic bottles and containers for water, beverages, cleaning products, wine, medical products, pesticides and chemical products.
1. Full Servo Drive System
The machine uses servo-driven systems for key mechanical movements, including stretching, material transfer, mold cavity operation and preform distribution. Compared with traditional cylinder-driven systems, servo control provides more precise motion control, stable operation and improved production efficiency.
2. High-Speed PET Bottle Production
The four-template structure and double mold-opening and closing operation help shorten clamping time and increase production efficiency. The available 8-cavity configuration has a theoretical output range of 12,000–16,000 bottles per hour, depending on production conditions and bottle design.
3. Infrared Preform Heating System
The PET blow molding machine uses infrared heating with preform rotation and rail revolution to distribute heat more evenly. The height and width of the heating lamps and reflectors can be adjusted according to different preform structures.
An automatic temperature-control system helps maintain a stable heating environment during continuous production.
4. Energy-Efficient Heating Design
The reduced heating distance in the oven helps lower heat loss and improve heating efficiency. Yaoshi states that the optimized heating system can achieve more than 30% energy savings compared with traditional blow molding machines, depending on operating conditions.
5. Stable Mold Clamping System
The high-pressure double crank-arm connecting rod structure provides strong mold-clamping force. The opening speed and distance can be adjusted according to production requirements, supporting stable bottle forming during high-speed operation.
6. Automatic Preform Feeding
The rotary and soft preform inlet system helps maintain stable preform feeding while protecting the preform neck. Servo-driven material transfer and preform distribution improve positioning accuracy and production stability.
7. Safety Interlock System
Each major mechanical action is equipped with a safety self-locking function. When an abnormal condition occurs during a process, the control system can automatically switch the machine to a safe state.
8. Low Bottle Rejection Rate
The existing product information specifies a finished-bottle rejection rate of less than 0.2% under the stated production conditions. Actual results may vary according to bottle design, preform characteristics and operating parameters.
9. Easy Operation and Maintenance
The machine supports both manual and automatic operating modes. Its clearly arranged valve system, PLC control and remote maintenance capability are designed to simplify operation, troubleshooting and routine maintenance.
10. Reliable Core Components
Yaoshi uses servo drives, programmable motion controllers, pneumatic components and high-pressure blow molding valve groups to build a coordinated control and pneumatic system. Components are matched and tested to support continuous high-speed operation.

Why Choose a Servo PET Blow Molding Machine?
A servo-controlled PET bottle blowing machine provides more precise control over key mechanical movements than conventional pneumatic systems. Servo stretching, transfer and mold operations can help improve repeatability while supporting high-speed production.
For manufacturers producing large quantities of PET bottles, the combination of 8-cavity molding, automated preform handling and optimized infrared heating provides a practical solution for increasing output while controlling energy and labor costs.
The machine's heating system is also designed to maintain consistent preform temperature, which is important for stable bottle forming and product quality.
Production Process
The automated bottle production process generally follows these steps:
PET Preform Feeding → Preform Heating → Servo Stretching → High-Pressure Blow Molding → Mold Opening → Bottle Output
The preform heating section prepares the PET material for stretching and molding, while the servo-driven system controls the key mechanical movements. After high-pressure air forms the heated preform against the mold, the finished bottle is released and transferred to the downstream production line.
Compatible Production Lines
The PET blow molding machine can be integrated with downstream beverage and packaging equipment, including:
Water filling lines
Carbonated soft drink filling lines
Juice filling lines
PET bottle packaging lines
Bottle conveying systems
Filling and capping equipment
For Yaoshi's existing website structure, the product can naturally link to the Bottled Water, Carbonated Soft Drinks, Juice Hotfill / Ultra-clean / Aseptic and other solution pages. The current site already organizes these applications under its Solutions section.
