High-Performance 72-Cavity 18g PET Preform Injection Molding Line – Advanced Solution for High-Speed Beverage Packaging Production

In today's highly competitive beverage packaging industry, efficiency, stability, and precision are the key factors that determine a manufacturer's success. To meet the increasing global demand for high-output PET preform production, we proudly introduce our 72-cavity 18g PET preform injection molding machine integrated production line, designed for ultra-high efficiency, stable performance, and intelligent automation.

This system is developed for manufacturers producing standard lightweight PET preforms widely used for 500ml bottled water, carbonated drinks, edible oil packaging, and beverage containers. With cutting-edge injection technology and optimized system integration, this production line ensures maximum output with minimal energy consumption and labor cost.

1. Ultra-High Productivity with 72-Cavity Mold Design

At the heart of this system is a 72-cavity high-precision preform mold, specially engineered for 18g PET preforms. This multi-cavity design significantly increases production efficiency while maintaining uniform product quality across all cavities.

With an optimized cycle time of approximately 8–10 seconds per cycle, the system can achieve extremely high hourly output, making it ideal for large-scale beverage packaging factories. Each cavity is precisely balanced to ensure consistent wall thickness, weight accuracy, and neck finish precision.

The 72-cavity configuration allows manufacturers to:

• Maximize production capacity per cycle
• Reduce per-unit production cost
• Improve overall machine utilization rate
• Meet large-volume orders efficiently

2. Advanced PET Injection Molding Technology

The injection unit of this machine is specially designed for PET material processing. PET requires high plasticizing performance and precise temperature control to ensure optimal crystallization and transparency.

Key features include:

• High-torque plasticizing system for stable PET melting
• Precise temperature control for barrel and nozzle
• Optimized screw design for uniform material mixing
• High-speed injection for reduced cycle time

These technologies ensure that each preform produced has excellent clarity, mechanical strength, and consistent dimensional accuracy.

3. Energy-Efficient Servo Hydraulic System

The machine adopts a high-efficiency servo hydraulic system, which intelligently adjusts power output according to production demand. Compared with traditional hydraulic systems, it significantly reduces energy consumption while improving response speed and stability.

Benefits include:

• Up to 30–50% energy savings
• Lower noise levels during operation
• Faster injection response time
• Reduced hydraulic oil temperature rise

This makes the production line not only cost-effective but also environmentally friendly, aligning with modern sustainable manufacturing standards.

4. Fully Integrated Automation System

To achieve fully automated production, the system can be equipped with a complete auxiliary line, including:

• Automatic hopper dryer system
• Central material loading system
• Mold temperature controller
• Preform conveyor belt system
• Automatic take-out robot
• Preform cooling and sorting unit

The integration of automation reduces manual labor dependency and ensures continuous, stable production 24/7.

With robotic handling, preforms are removed from the mold instantly after injection, improving cycle efficiency and reducing the risk of contamination or deformation.

5. High-Precision Mold & Neck Finish Stability

The mold system is manufactured with high-grade tool steel and precision machining technology. It ensures excellent durability and long service life even under high-speed production conditions.

Key advantages:

• Excellent cavity balance for uniform product quality
• Precise neck finish control for bottle sealing performance
• High wear resistance for long-term production stability
• Easy maintenance and fast mold change design

The 18g preform is widely used in the beverage industry, requiring strict dimensional tolerance, especially in the neck area. Our system ensures every preform meets international packaging standards.

6. Intelligent Control System

The machine is equipped with a modern PLC control system with a user-friendly interface, allowing operators to easily monitor and adjust production parameters.

Functions include:

• Real-time production monitoring
• Automatic alarm system
• Production data recording
• Temperature and pressure control visualization
• Remote maintenance support (optional)

This intelligent system ensures stable production and minimizes downtime caused by human error or system failure.

7. Wide Application Range

The 72-cavity 18g PET preform production line is suitable for a variety of applications, including:

• Bottled drinking water
• Carbonated beverages
• Juice packaging
• Edible oil containers
• Daily chemical packaging

Its versatility makes it an ideal choice for both large-scale beverage factories and PET preform manufacturers.

8. Reliable Performance for Global Markets

Our PET preform injection molding line is designed to meet international standards and has been widely exported to Asia, the Middle East, Africa, and South America. It is capable of adapting to different voltage requirements and production environments.

We provide full technical support, installation guidance, and after-sales service to ensure smooth operation and long-term reliability for global customers.
