Product Introduction
A fully automatic blow moulding machine, also known as an automatic blow moulding machine or fully automatic blow moulding system, is designed to produce hollow plastic containers at high speed and with consistent quality. As a key solution for automatic blow moulding machine production, it integrates extrusion, moulding, cooling, and product ejection into a fully automated process. Depending on the model and bottle size, production capacity can reach up to 2,000 bottles per hour, making it suitable for beverage, chemical, pharmaceutical, and household product manufacturing.
Structure of the Bottle Blowing Machine
An automatic blow molding machine primarily consists of an extrusion system, a mold system, a mold-clamping mechanism, a blowing system, hydraulic and pneumatic systems, and an electrical control system. These modules work in coordination to achieve fully automated production, covering the entire process from the melting of plastic raw materials to molding, cooling, and demolding.
- Extrusion System: Responsible for heating, plasticizing, and extruding plastic pellets to form a uniform, stable parison; this serves as the foundation of the blow molding process.
- Die Head: Extrudes molten plastic evenly into a tubular parison; single-layer or multi-layer die heads can be configured based on product requirements.
- Blow Mold: Determines the product’s appearance, dimensions, and structure; high-precision molds enhance product consistency and surface quality.
- Clamping Mechanism: Controls rapid mold opening and closing while providing a stable clamping force to ensure a tight seal during the blow molding process.
- Blowing System: Uses compressed air to inflate the parison against the inner mold walls to form the final product, while regulating blowing pressure and duration.
- Hydraulic or Servo Drive System: Provides power for mold clamping, opening, and part ejection; servo systems further reduce energy consumption and improve control precision.
- Cooling System: Rapidly cools the mold and product to accelerate molding speeds, thereby enhancing production efficiency and dimensional stability.
- Automatic Trimming and Part Removal System: Automates flash removal, part extraction, and conveying, reducing manual labor and improving production continuity.
- Electrical Control System: Utilizes PLC and touchscreen controls for process parameter setting, operational monitoring, fault alarms, and data management.

Working Principle of a Bottle Making Machine
In the fully automatic blow molding machine process—comprising cold preform intake, heating and softening, mechanical stretching, low-pressure pre-blowing, high-pressure blowing with mold cooling, and final cooling and ejection—bottle formation is achieved through the coordinated interaction of temperature control, mechanical stretching, and low- and high-pressure air.
- Automatic Preform Feeding (Preform Alignment Process)
The preform aligner organizes scattered preforms, ensuring they are uniformly oriented and conveyed in an orderly manner, while automatically sorting out and rejecting non-conforming preforms. - Infrared Oven Heating and Softening
Zoned infrared lamps precisely heat the preform body to the softening temperature, ensuring the bottle neck remains at a low temperature to prevent deformation, while air cooling evenly distributes the temperature throughout the preform. - Transfer of Heated Preforms to Mold Clamping
A gripper picks up the heated preforms and feeds them into the mold. The equipment locks the mold in place to ensure no air leaks or mold openings during the blow molding process. - Stretching + Low-Pressure Pre-Blow Molding
Stretching rods elongate the preforms longitudinally, while low-pressure air simultaneously expands the preforms to prevent wall adhesion and uneven wall thickness. - High-Pressure Blow Molding and Shaping
High-pressure air at 30 bar is injected to forcefully expand the soft preform, causing it to fully conform to the inner walls of the mold and replicate the bottle’s complete exterior shape. - Water-Cooled Mold Cooling and Curing
A circulating water cooling system built into the mold rapidly dissipates heat, allowing the softened PET to harden and set to its final dimensions, thereby preventing shrinkage and deformation of the finished product. - Pressure Relief, Mold Opening, and Product Ejection
High-pressure gas is vented from the bottle. Once the mold opens, the clamping mechanism releases, and the finished bottle automatically drops out, completing a single cycle.

Process Description
The air compressor produces compressed air → the filter removes impurities → the air receiver stabilizes the pressure and stores the air → the refrigerated dryer removes moisture and dries the air, supplying a clean air source to the blow molding station; simultaneously, the chiller provides circulating cooling water; the preform sorter organizes the preforms and feeds them into the heating oven for softening; the softened preforms then enter the blow molding machine to undergo stretching, high-pressure inflation, and cooling to set the shape. The entire system operates in tandem to achieve automated bottle production.
- Air Compressor
Generates the high- and low-pressure compressed air required for blow molding, providing the air power for the pre-blow and molding processes. - Air Filter
Performs multi-stage filtration to remove dust, oil, and impurities from the compressed air, preventing pitting and defects on the inner walls of the bottles. - Air Receiver Tank
Stores a sufficient volume of compressed air and stabilizes the pressure in the piping system, ensuring a large, instantaneous supply of compressed air during blow molding without a pressure drop. - Cooling Dryer
Removes moisture from the compressed air to prevent white haze and water mark defects caused by moisture-laden airflow coming into contact with high-temperature preforms. - Chiller
Circulates low-temperature cooling water to the mold and oven, used respectively for cooling and setting the bottle body and for maintaining a constant temperature in the oven. - Preform Organizer (Preform Decoder)
Automatically organizes scattered PET preforms, conveying them in an orderly manner with the bottle necks uniformly facing upward, and automatically sorts out and removes damaged preforms. - Preform Heating Unit (Infrared Oven)
Zoned infrared lamps uniformly heat the preforms to a softened state, while low-temperature protection at the bottle neck prevents deformation; an air circulation system ensures even temperature distribution. - Bottle Blow Molding Machine
The heated preforms are fed into the mold, where they undergo mechanical stretching, low-pressure pre-blowing, and 30 bar high-pressure inflation, conforming to the mold and forming the finished bottles through water-cooling.
