Equipment type
| Types of machines | Description |
| Linear stretch blow molding machine | Uses linear motion to stretch and blow the preform into a bottle. Cost-effective, with a good balance of production speed and quality. |
| Rotary stretch blow molding machine | Uses rotary motion to stretch and blow the preform. Faster production speeds compared to linear machines. Can produce higher quality bottles. |
Working principle of bottle blowing machine
1. Preform heating:
– The preform is evenly heated to the appropriate blow molding temperature by the heating system.
2. Preform conveying and positioning:
– The heated preform is conveyed to the blow molding mold and accurately positioned.
3. Stretching and initial blow molding:
– The stretch rod stretches the preform vertically, and low-pressure air is injected in the initial blow molding stage to make the preform expand initially.
4. High-pressure blow molding:
– High-pressure air is injected into the preform to make it fully expand and form into the final bottle shape.
5. Cooling and shaping:
– The blown bottle is cooled and shaped in the mold.
6. Demolding and conveying:
– After cooling, the bottle is removed from the mold and conveyed to the next process.

Features and benefits
Intelligent control system:
– The whole working process is controlled by human-machine interface (HMI), with functions such as automatic feeding, automatic swinging, and automatic unloading. Each action cylinder is equipped with a magnetic induction switch and connected to the PLC to control each step of the operation and detect the status of each cylinder in real time. If the previous step is not completed, the system will automatically wait for the previous step to be completed before proceeding to the next step. The system has automatic alarm and fault display functions, and the PLC will display the problem, which is convenient for quick troubleshooting.
High efficiency and accuracy:
– The equipment runs fast, the position control is accurate, and the action is smooth. For different bottle sizes, a cross double crank booster clamping system is adopted, which has strong clamping force and quick mold opening adjustment, saving time and improving production efficiency.
Efficient heating system:
– Far infrared heating lamps are used, which have strong penetration to ensure uniform heating of preforms. The heating system is equipped with PLC or electronic voltage regulator, which can control each group of temperature separately to meet different heating needs. The unique preheater design can add necessary additives at the same time during the heating process, adjust the heating gap according to the size of the bottle, shorten the heating channel and reduce energy consumption.
Air supply system:
– Equipped with micro-blowing, high-pressure blowing and low-pressure action air supply system to ensure sufficient air for different products. Unique high-pressure air recovery device to further reduce energy consumption.
Operation mode and automation:
– The operation is divided into manual and automatic procedures. Assembly and inspection are manually operated, and the production process is fully automatic to ensure that the production process is fully automated, high-quality and pollution-free.
Simple operation and maintenance:
– The fully automatic bottle blowing machine has low investment, high efficiency, easy operation, simple and safe maintenance, and is suitable for all types of enterprises to carry out efficient bottle production.
Advantages Summary：
The fully automatic bottle blowing machine ensures high-quality production of bottles through the optimization of intelligent control, precise operation and efficient heating system. It has the characteristics of friendly human-machine interface, smooth operation, high and stable output, low energy consumption and high degree of automation. It adopts a cross double crank booster clamping system with strong clamping force, stable and reliable bottle blowing action, and simple operation and maintenance design, making it an ideal choice for beverage factories to produce bottles.
Maintenance and precautions
Regularly check and maintain mold clamping, heating, blowing and other components.
Properly store and handle preform raw materials.
Monitor temperature control system and energy consumption.
Adjust machine settings according to different bottle sizes and production requirements.
Ensure that automatic feeding, ejection and transfer systems are properly aligned and functioning properly.
