72-Cavity High-Capacity PET Preform Injection Molding Machine: Maximum Output for Large-Scale Production
APEX Machinery proudly presents our 72-Cavity High-Capacity PET Preform Injection Molding Machine—a precision-engineered system designed to deliver exceptional productivity for large-scale preform manufacturers. As the demand for PET packaging continues to grow globally, our 72-cavity solution provides the ideal balance of high output, energy efficiency, and consistent quality, enabling customers to maximize their return on investment in competitive markets .
Unmatched Productivity for High-Volume Production
The 72-cavity configuration represents the optimal choice for manufacturers requiring substantial daily output without the complexity of higher cavitation systems. Our advanced system delivers production rates of 23,000 to 31,000 preforms per hour, depending on preform weight and specifications . With typical cycle times ranging from 9 to 15 seconds for standard preform weights, the machine achieves continuous daily outputs exceeding 345,000 preforms in 24-hour operation .
This exceptional productivity makes our 72-cavity system ideal for:
Large-scale beverage companies with high-volume bottle requirements
Professional preform converters serving multiple clients
Contract manufacturers requiring reliable, high-output production capacity
Integrated packaging operations combining preform, cap, and bottle manufacturing
Advanced Post-Mold Cooling Technology for Faster Cycles
At the heart of our 72-cavity system's high-speed performance lies an innovative cooling and handling system that addresses the primary bottleneck in PET injection molding—cooling, which can account for up to 80% of total cycle time. Our technology features:
Three-stage post-mold cooling system with multi-position take-out plates that remain active for up to 85% of the overall cycle
Up to 216 cooling positions (72 cavities × 3 stages), ensuring preforms achieve dimensional stability before discharge
Internal preform cooling capability that effectively reduces the inner surface temperature without relying heavily on compressed air, unlike conventional systems that only cool the outer surface
Low ejection temperatures preventing deformation and scratching during automated handling
This intelligent cooling approach dramatically reduces in-mold cooling time requirements, enabling cycle times as low as 9 seconds for 15g preforms while maintaining excellent preform quality .
Precision Engineering for Consistent Quality
APEX's 72-cavity preform system incorporates precision components that ensure shot-to-shot repeatability and minimal weight variation across all cavities:
High-performance plasticizing unit with specially designed PET screws featuring a 25:1 L/D ratio for superior melt quality and homogeneity
Two-stage plasticizing capability enabling ample injection quantity for various preform weights up to 50g
Special screw design that increases torque while reducing shear force to avoid material degradation
Advanced pneumatic needle valve hot runner systems with individual temperature control for each nozzle, ensuring balanced filling across all 72 cavities and eliminating common defects such as bottom whitening or drawdown
Flexible platen design with linear bearings that distribute clamp force evenly across the mold face, allowing for 10-30% lower clamp tonnage while reducing mold wear and improving part quality
Weight difference between cavities is maintained within tight tolerances, ensuring consistent preform quality for downstream blow molding processes.
Robust Construction for 24/7 Industrial Operation
Built to withstand the rigors of continuous industrial production, our 72-cavity system features:
Clamping forces of 380 to 500 tons ensuring consistent mold closure under high-speed operation
Generous tie-bar spacing (up to 820×820mm) accommodating 72-cavity molds with ease
Linear bearing support systems that reduce mold wear by improving platen alignment and perpendicularity, while providing a grease-free molding environment
High-quality global components from renowned manufacturers ensuring long-term reliability in demanding production environments
Energy Efficiency and Sustainability Features
In alignment with global sustainability trends, our 72-cavity preform machine incorporates features that significantly reduce energy consumption:
Accumulators from world-renowned manufacturers that optimize energy usage during injection cycles, increasing performance while reducing power consumption
Reduced specific energy consumption compared to lower cavitation machines, as energy costs are distributed across more preforms per cycle
Compatibility with recycled PET (rPET) materials, supporting up to 100% rPET content with appropriate auxiliary systems
Efficient cooling system design with optimized water flow management ensuring homogeneous temperature distribution
Maximum Preform Specifications and Flexibility
Our 72-cavity system accommodates a wide range of preform designs:
Maximum preform weight: Up to 50g depending on configuration
Quick changeover capabilities allowing efficient transitions between different preform specifications
Integrated Automation and Smart Control
Our machines feature advanced control systems designed for ease of use and operational optimization:
PC-based controls with user-friendly HMI touchscreens managing all functions of the PET production system
Side-entry servo robots with three-station cooling jigs for efficient preform extraction and handling
Real-time production data display including speed, count, and efficiency metrics
Remote connectivity for monitoring, diagnostics, and maintenance support
Integration capability with auxiliary equipment including dryers, loaders, chillers, and compressed air systems
