Fully Automatic PET Blowing Machine

Full automatic 4 cavity pet bottle blowing machine

The efficiency of the YC-4000A fully automatic PET blowing machine is directly reflected in its significantly increased production capacity per unit time. Compared to common dual-cavity equipment, it simultaneously blows four bottles in each molding cycle. Equipped with four servo motor system independent processes-feeding, shifting, stretching, and bottle mold clamping-the molding cycle for a single 500ml bottle can be optimized to 2.62-2.4 seconds, with one set machine producing 5500-6000 bottles (3600 seconds / 2.4 seconds * 4 cavities = 6000 bottles/hour). The production capacity can meet the large-scale, centralized production needs of medium to large-sized beverage brands for a single product category. A completed line can support a massive daily market consumption, simplifying factory production line layout and reducing the number of equipment, floor space, and personnel required to achieve the same total production capacity.

Precise temperature control

Equipped with 32 1500W infrared heating lamps and 4 independent heating furnaces, combined with PLC dynamic temperature adjustment, the fully automatic PET blowing machine can achieve uniform heating of preforms, and the temperature error is controlled within ±1℃, ensuring uniform heating and reducing the defect rate of finished products.

Easy to operate

The fully automatic PET blowing machine is equipped with a 7-inch multi-language human-machine interface (HMI) touch screen, which monitors temperature, pressure, and production speed in real-time. The system can automatically alarm and perform fault diagnosis, lowering the operating threshold. Operators can easily complete recipe calls and parameter adjustments.

The fully automatic PET blowing machine system is a continuous, closed-loop automated process. The system begins with the automatic feeding and oriented arrangement of PET preforms. The preforms enter an infrared heating furnace via a stainless steel conveyor belt, where they are uniformly heated in a precisely temperature-controlled, segmented heating zone to achieve an ideal plastic state. The heated PET preforms are then transferred to the blow molding die. During blow molding, high-pressure gas is injected in stages (pre-blowing, high-pressure blowing) to cause the preforms to expand and fit tightly against the mold cavity. Cooling water quickly shapes the product into the designed form. After molding, the products are conveyed to subsequent inspection, labeling, or filling stages. The entire process does not need human intervention; each station is controlled by PLC control. It achieves high speed and efficient conversion from preform to finished bottle.

1, What are the advantages of a fully automatic PET blowing machine?

The core advantage of an automatic PET blowing machine lies in its superior production efficiency. By integrating preform loading, heating, blow molding, cooling, and bottle unloading into a continuous automated cycle, it achieves stable, uninterrupted production 24/7. Compared to semi-automatic equipment, its production cycle time is significantly shortened, and single-machine capacity can be increased several times. High-speed models can produce thousands or even tens of thousands of bottles per hour, fully meeting the market demand for large-scale production, significantly shortening delivery cycles, and improving companies' order response speed and market supply capabilities.

2, Why prioritize servo-driven automatic PET blowing machine?

Compared to traditional hydraulic drives, servo drive systems precisely consume energy only during equipment operation, eliminating idle losses, it reduce equipment energy consumption by 20% to 25%. The long-term electricity savings are substantial, reducing the production cost of individual products.

3,How to achieve rapid bottle mold replacement in an auto PET blowing machine?

Our equipment was designed with it in mind from the outset. Each machine is equipped with a mold-exchanging robot for quick mold replacement, enabling a changeover within 30 minutes.It reduces equipment downtime and extends equipment utilization efficiency.
