Energy-Efficient 64-Cavity PET Preform Injection Molding Machine

As the packaging industry evolves toward greater sustainability and higher productivity, APEX Machinery introduces our flagship Energy-Efficient 64-Cavity PET Preform Injection Molding Machine. This advanced system is engineered to meet the demands of high-volume preform production while significantly reducing energy consumption and operating costs. By integrating cutting-edge servo technology, precision hot runner systems, and intelligent process controls, our 64-cavity machine delivers exceptional output with minimal environmental impact.

Maximized Productivity with Multi-Cavity Efficiency

Our 64-cavity preform machine is designed for manufacturers who require high throughput without compromising quality. With the capability to produce up to 23,000 to 31,000 preforms per hour depending on preform weight and specifications, this machine enables substantial increases in production capacity . Typical cycle times range from 9 to 15 seconds for standard preform weights, allowing continuous daily outputs exceeding 345,000 preforms . This level of productivity makes the 64-cavity system ideal for large-scale preform converters, beverage companies, and packaging manufacturers serving mass-market demands.

Advanced Servo Energy-Saving Technology

At the core of our energy-efficient design is a state-of-the-art servo motor drive system that revolutionizes power consumption in injection molding . Unlike traditional hydraulic systems that operate continuously, our servo-driven machine dynamically adjusts motor speed and torque to match actual load requirements during each phase of the molding cycle—clamping, injection, cooling, and ejection. During cooling periods, the servo motor can come to a complete stop, achieving zero power consumption . This intelligent power management results in energy savings of 30% to 60% compared to conventional hydraulic machines .

The servo system also delivers faster response times (as quick as 0.05 seconds), reducing cycle times and increasing overall productivity by 10% to 15% . Additionally, precise closed-loop control ensures repeatable injection accuracy with metering error of less than 0.3%, guaranteeing consistent preform quality across every cavity .

Precision Hot Runner System for Superior Quality

The performance of a 64-cavity preform machine depends heavily on the hot runner system. APEX's machines feature an advanced needle valve hot runner system that ensures precise control over melt flow and gate quality . Key advantages include:

• Individual cavity pressure control that eliminates flow imbalances and ensures uniform filling across all 64 cavities

• Elimination of gate vestige through precise valve pin actuation, ensuring clean preform neck finish for subsequent blow molding

• Reduced material waste by up to 15-20% compared to open hot runner systems, as no manual gate trimming is required 

• Temperature control accuracy within ±1°C using high-quality heating elements and PID temperature controllers, preventing material degradation 

This level of precision maintains product qualification rates above 99.5%, significantly reducing scrap and improving overall equipment effectiveness .

Optimized Cooling System for Faster Cycles

Cooling efficiency directly impacts cycle times and preform quality. Our 64-cavity machine incorporates a high-performance cooling system with spiral cooling channels and multi-stage temperature control . Key features include:

• Central splitter plate design ensuring balanced cooling water distribution to all cavities

• Graphite copper plates between sliders and pushing plates to reduce friction and improve heat transfer at threaded joint areas 

• High-pressure turbulent cooling water that rapidly extracts heat from preforms, reducing crystallization and improving transparency

• Intelligent temperature regulation maintaining mold body temperature between 40-55°C for optimal processing conditions 

This advanced cooling architecture enables consistent preform ejection at lower temperatures, reducing overall cycle times and improving dimensional stability.

Enhanced Energy-Saving Features

Beyond servo drive technology, our 64-cavity preform machine incorporates multiple energy-saving innovations:

• High-efficiency plasticizing unit with specially designed PET screws featuring optimized L/D ratios (typically 25:1) for superior melt quality at lower processing temperatures 

• Variable frequency drives (VFDs) on auxiliary equipment that adjust motor speeds based on actual demand 

• Energy recovery systems that capture and reuse heat from hydraulic oil and cooling water for preheating raw materials 

• Low-friction mechanical components and optimized toggle systems that reduce energy losses during clamping and ejection 

These combined technologies ensure that our machine delivers the lowest specific energy consumption per preform in its class.

Integrated Smart Control System

Our machines feature an advanced PLC control system with a large HMI touchscreen that provides real-time monitoring and optimization of all process parameters . Operators can:

• Track energy consumption per shot and analyze trends for continuous improvement 

• Monitor cavity-specific temperature, pressure, and filling data

• Access pre-programmed recipes for quick changeovers between preform designs

• Receive predictive maintenance alerts based on sensor feedback

• Integrate with factory-wide Manufacturing Execution Systems (MES) for Industry 4.0 connectivity 

This smart control capability enables data-driven decision-making that further enhances energy efficiency and productivity.
