48-Cavity PET Preform Production Solution: The Ideal Balance of Productivity and Flexibility

APEX Machinery proudly presents our 48-Cavity PET Preform Production Solution—a precision-engineered injection molding system designed to deliver the perfect balance between high-volume output and operational flexibility. Whether you are an emerging brand expanding into new markets, introducing new SKUs, or an established producer seeking to optimize production capacity, our 48-cavity system provides the confidence to grow while maintaining the highest quality standards .

Optimized for Mid-to-High Volume Production

The 48-cavity configuration represents the sweet spot for manufacturers requiring substantial output without the complexity of higher cavitation systems. Our solution delivers production rates of 17,000 to 25,000 preforms per hour, depending on preform weight and specifications, with typical cycle times of 9 to 12 seconds . This level of productivity makes it ideal for:

• Emerging beverage brands entering new markets with annual output requirements of 150–200 million preforms 

• Established producers adding new SKUs or special production runs

• Contract manufacturers serving multiple clients with varying preform specifications

• Regional bottlers requiring reliable, cost-effective preform supply

Advanced Cooling Technology for Faster Cycles

At the heart of our 48-cavity system's high-speed performance lies an innovative post-mold cooling and handling system that addresses the primary bottleneck in PET injection molding—cooling, which can account for up to 80% of the total cycle time . Our technology features:

• Three-stage cooling system with multi-position take-out plates that remain active for up to 85% of the overall cycle 

• Up to 144 cooling positions (48 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 

• Low ejection temperatures (approximately 40°C for the neck finish and 20°C for the preform body), preventing deformation and scratching during handling 

This intelligent cooling approach dramatically reduces in-mold cooling time requirements, enabling cycle times as low as 9 seconds while maintaining excellent preform quality .

Precision Engineering for Consistent Quality

APEX's 48-cavity preform system incorporates precision components that ensure shot-to-shot repeatability and minimal weight variation:

• 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 

• 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 48 cavities and eliminating common defects 

• Flexible platen design that distributes 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.

Energy Efficiency and Sustainability

In alignment with global sustainability trends, our 48-cavity preform machine incorporates features that significantly reduce energy consumption and support recycled material processing:

• Servo-driven hydraulic systems with 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 to help meet sustainability goals and evolving post-consumer resin requirements 

• Efficient cooling system design with pump-controlled temperature management that ensures homogeneous water temperature at every process stage 

Robust Construction for 24/7 Operation

Built for industrial-scale continuous production, our 48-cavity system features:

• Clamping forces ranging from 260 to 500 tons depending on preform weight requirements, ensuring consistent mold closure under high-speed operation 

• Generous tie-bar spacing accommodating 48-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 

• Durable construction with high-quality global components ensuring long-term reliability in demanding production environments

Smart Control Systems for Real-Time Optimization

Our machines feature advanced control systems with user-friendly HMI touchscreens that manage all functions of the PET production system . Operators benefit from:

• Faster cycle times through optimized process control

• Improved shot-to-shot repeatability ensuring consistent quality across production runs

• Remote connectivity for monitoring and diagnostics 

• Centralized control of molding system and auxiliaries from a single interface 

• Adaptive system pressure that automatically adjusts oil pressure to suit specific applications while conserving energy 

Rapid Changeover and Flexibility

Our 48-cavity system is designed for manufacturers who need to respond quickly to changing market demands:

• Quick mold changeover capability—as fast as 30 minutes for complete plate replacement, whatever the number of cavities 

• Flexible neck finish compatibility supporting thread diameters from 30mm to 48mm 

• Adaptable preform length capability up to 190-220mm depending on configuration 

• Compatibility with legacy tooling for larger neck applications, adding flexibility for diverse production requirements 

Applications Across Industries
