Fully Automatic Servo Blow Molding Machine

Features

Our machine with full servo electronic CAM drive, which can ensure that the machine will be much stable and fast in production.

1. Preform Split System: Preform Split by servo motor, shorten the conveying track, but  supply enough preforms completely.

2. Servo Shift System: the main chain adopts the way of servo drive bearing connection, which can ensure the long-term use of preform movement, with reduced impact, low noise, long life and other advantages.

3. Heating System: The ruby heating lamp can heat the preforms better so that the stretching more uniform and high transparency; The lamp with single side coated, shorten heating time, low energy consumption, and improve production, and each layer of the lamp can be adjusted the temperature separately, also easy to slope adjustment with up and down, front and back according to the different preforms.

4. Servo Clamping System: with high pressure pressurization clamping, no expansion phenomenon, and the clamping line is very good, easy to replace the mold because there have  positioning plate on the clamp plate, which can be replaced very fast.

5. Servo Stretch System: Parker, FESTO, SMC and other imported pneumatic components, blowing cycle time can be adjusted, equipped with low-pressure gas recovery system, each stretch rod can be adjusted separately with high flexibility.

6. Electronic System: Schneider,Sanrex,OMRON and other imported electronic control components, all Xinjie brand with sport PLC ,servo system and touch screen . We can update the machine by WIFI remote control and debugging , which can help customers solve various problems and processes. The touch screen can be converted into 6 languages,  perfect monitoring sensor Settings, automatic fault display function, automatic statistics of production and efficiency.

7. Water Cooling system: There is a water cooling channel under the heating box connected by copper tube, which can protect the neck cooling during the heating of the preform. The cooling system also connect to the mold and the bottom to keep the bottle wihtou deformation and improve the production .

The Fully Automatic Servo Blow Molding Machine is a stretch blow molding system that uses servo-driven mechanisms for precise and adjustable preform handling. It automates the production of PET bottles and containers with consistent quality, offering flexible operation for multiple container sizes and shapes.

Key Definitions

3. Working Principle

The machine uses a two-stage stretch blow molding process to produce high-quality beverage and food containers. The servo system ensures precise movement, reducing material stress and improving bottle consistency.

Production Workflow

1. Preform Feeding
   Preforms are automatically loaded into the feeding system and aligned for processing.

2. Infrared Heating
   Preforms are heated evenly to a specific temperature for optimal stretching.

3. Stretching Stage
   Servo-driven stretch rods elongate preforms vertically, ensuring uniform molecular orientation.

4. High-Pressure Blowing
   Compressed air inflates the preforms into molds, forming the container shape.

5. Cooling Stage
   The mold cools the container uniformly, preventing deformation.

6. Automatic Ejection
   Finished bottles are discharged efficiently for downstream packaging or labeling.
