Combi Block Blowing-filling-capping All in One Machine

The Combi Block Blowing-Filling-Capping All-in-One Machine is an advanced packaging solution that integrates three major processes—bottle blowing, liquid filling, and cap sealing—into one seamless system. Compared with traditional separated blowing and filling systems, the combiblock blowing filling capping eliminates air conveyors, reduces bottle scratches, and increases production stability.

Designed for medium and large-scale beverage manufacturers, the system supports multiple product types, including purified water, carbonated drinks, flavored beverages, dairy drinks, coffee, edible oil, and premium products such as bird nest beverages.

As a high-automation water filling system blowing filling capping machine, it delivers exceptional hygiene, faster changeovers, and lower energy consumption while maintaining perfect precision.

Key Features & Advantages of Combi Block Blowing-Filling-Capping Machine

The blowing unit of the combiblock blowing-filling-capping machine features a specially designed secondary blowing system that monitors the pressure curve of the bottle stretch process in each cavity in real time. This provides precise parameters for technical adjustments, ensuring consistent bottle quality across high-speed production.

The manipulator transfer technology, driven by a high-precision cam mechanism, handles preforms and bottles efficiently, completing picking, sending, and ranking automatically in sync with mold opening and closing. This eliminates the risk of contamination and significantly improves operational efficiency in the 3-in-1 water filling system blowing filling capping machine.

The cam-controlled mold frame allows independent control of blowing parameters for each cavity. A specialized mold locking and pressurizing system ensures reliable sealing under various pressures and supports precise adjustments. Stretch rods accurately control the axial stretching of preforms, and by fine-tuning the first and second blow stages, the machine achieves ideal bottle wall thickness distribution for enhanced strength and uniformity.

The innovative coaxial rotary bushing design, equipped with deep groove ball bearings, maintains concentricity between the outer sleeve and core axis, reducing wear on the rotary sealing ring. An additional water back channel prevents leakage, ensuring stable and hygienic operation throughout the high-speed production process of the blowing-filling-capping combiblock.

Working Process of Combi Block Blowing-Filling-Capping Machine

Preform Feed-in and Unscrambling

The Combi Block starts with a fully automatic preform feed-in and unscrambling system, designed for high-speed beverage production lines from 12,000–36,000 BPH. This section ensures every PET preform enters the blowing module in perfect orientation, stable condition, and contamination-free.

Key Features of Preform Feed-in & Unscrambling System

• Fully Automatic Elevator & Hopper Feeding

Preforms are lifted smoothly from the hopper to the unscrambler, preventing scratches, deformation, and contamination.

• High-Precision Preform Orientation

The rotary unscrambler arranges preforms with 100% correct neck-up positioning, enabling continuous, high-speed transfer to the heating oven.

• Neck-Protection & Anti-Jamming Design

Special neck-holding rails and buffer channels ensure gentle handling and avoid collisions even at ultra-high speeds such as 36,000 BPH.

• Integrated Inspection Mechanism

Optional vision detection checks deformities, black spots, unqualified neck finishes, and short shots before blowing.

• Energy-Saving Operation

Optimized transmission minimizes friction, while servo-driven feeding ensures lower power consumption and noise control.

• Compatible with Multiple Bottle Types

Suitable for water, juice, CSD, milk, edible oil, coffee, bird’s nest, and special-shape bottle preforms.

Oven Heating System

The oven heating system of the Blowing–Filling–Capping Combi Block is designed for energy efficiency, precise temperature control, and high-speed preform conditioning. By ensuring uniform and stable preform heating, the system prepares each preform for perfect bottle forming, even at production speeds of 12,000–36,000 BPH.

Key Features of Oven Heating System

• Infrared Lamp Heating with Independent Temperature Control

Each lamp zone can be individually adjusted to achieve accurate heating based on preform thickness, color, and material requirements.

• Optimized Air Circulation & Heat Balance

Ensures uniform heating, avoiding crystallization, deformation, or uneven stretching.

• Energy-Saving Reflector Plates

High-efficiency aluminum reflectors maximize heat utilization and reduce power consumption by 20–30%.

• Adjustable Preform Spacing & Servo Conveyor System

Enhances heating consistency while ensuring high-speed, stable transfer into the blow molding station.

• Neck Protection Cooling System

Dedicated cool-air channels keep preform necks in low temperature to avoid distortion during heating.

Blowing Unit (Servo Stretch + High-Pressure System)

The blowing unit is the core of the Combi Block, integrating servo-driven stretching, high-pressure blowing, and optimized mold cooling to form precise PET bottles for water, juice, CSD, milk, edible oil, coffee, or bird’s nest beverages.

Key Features of Blowing Unit

• Servo Stretching Rods

High-speed servo motors provide accurate stretching trajectory and pressure control, improving bottle consistency and mechanical strength.

• High-Pressure Blowing System (20–35 bar)

Ensures fast forming, clear bottle shape, and reduced energy consumption.

• Quick-Change Mold System

Enables rapid switch between different bottle shapes and volumes (200ml–2L).

• Optimized Cooling Circuit

Advanced cooling channels shorten molding cycles and enhance bottle clarity and hardness.

• Air Recovery System (Optional)

Reduces compressed air usage by 30–45%, significantly lowering operating cost for large-capacity lines like 24,000–36,000 BPH.

• Fully Enclosed Blowing Environment

Prevents dust contamination and ensures clean bottle output for sensitive beverage categories.

Filling Section

The filling module is directly connected to the blowing unit—no air conveyors—ensuring zero bottle contamination, stable high-speed transfer, and fully hygienic filling.

Key Features of Filling Section

• Electronic Flowmeter or Level-Control Filling

Supports water, juice, CSD, milk, coffee, functional drinks, and bird’s nest.

• Sanitary 316L Contact Parts

Suitable for acidic, high-viscosity, or sensitive liquid formulations.

• High-Speed Rotary Filling Valve

Ensures precise filling accuracy within ±1–2g.

• No-Bottle-No-Fill Protection

Intelligent star-wheel control prevents spillage and ensures stable production.

• CIP / SIP System Compatible

Fully automated cleaning ensures food-grade hygiene.

• Isobaric Filling for CSD (Optional)

Maintains carbonation levels with controlled pressure balance.

Capping Section

The final stage of the Combi Block ensures secure, hygienic, and consistent cap application at ultra-high speeds.
