Duo H Two-Platen Injection Molding Machines - High-Ton Injection Performance
The Plastic Metal Duo H series represents a high-performance two-platen (two-plate) injection molding platform engineered for large and complex plastic parts. Combining structural strength with precision motion control, Duo H machines deliver high tonnage performance, rapid cycle times, and consistent production stability across industrial applications.
Duo H systems are developed to support demanding manufacturing environments requiring large mould accommodation, deep cavity parts, and high throughput - ideal for automotive, industrial, logistics, and heavy-duty plastic production.
Wide Tonnage Range & Structural Capacity
The Duo H series covers a broad operating range suited for both medium and large applications:
• Clamping force range: 610 - 2110 tons
• Tie-bar spacing options up to 1700 × 1500 mm
• Maximum mould thickness accommodating deep cavitation
• Large platen surface to support oversized tool plates
This robust mechanical layout supports high structural rigidity and uniform force distribution, enabling stable mould closing forces even at maximum tonnage.
Two-Platen Design for Large Parts
The two-platen architecture ensures efficient force transmission and reduced machine footprint:
• Long opening strokes for deep cavities and extended tool heights
• Compact footprint compared to traditional toggle machines of similar tonnage
• High acceleration/deceleration capability for rapid cycle performance
Two-platen machines optimize room usage while ensuring maximum platen rigidity, making Duo H particularly effective for:
✔ Large pallet production
✔ Industrial containers and bins
✔ Automotive bumpers and structural components
✔ Storage & logistics products
Injection Capacity & Productivity
Duo H machines deliver impressive injection performance across a range of configurations:
• Shot volumes typically from 1000 to 7000+ cm³
• Shot weight range of 10 kg to 40+ kg (PS equivalent)
• High injection speeds with precise pressure control
• Plasticizing systems designed for high throughput
These values make the Duo H series suitable for producing thick-wall industrial parts as well as large structural components requiring high material mass and stability.
Energy-Efficient Servo & Hybrid Drives
Modern Duo H platforms are available with advanced servo-pump and hybrid drive systems, providing:
• Up to 30-60% energy savings compared to traditional hydraulic drives
• Automatic power adjustment based on process demand
• Reduced heat dissipation and lower cooling requirements
• Quiet operation with high dynamic performance
Hybrid configurations enhance energy efficiency, especially during long production cycles in continuous manufacturing environments.
High Precision & Repeatability
Even at high tonnage levels, Duo H machines maintain process accuracy and part consistency:
• Servo-controlled hydraulic circuits for stable pressure and flow
• Low vibration motion control systems
• Repeatable ejection and clamping cycles
• Accurate mould positioning for complex geometries
These features deliver production reliability even under the most demanding multi-shift operations.
Automation & Line Integration
Duo H systems are engineered for seamless integration with automated production lines:
• Robot-ready interfaces for part removal and palletizing
• Conveyor and material handling system compatibility
• In-line quality inspection system integration
• Full Industry 4.0 / Smart Factory communication support
This enables manufacturers to build high-capacity, fully automated injection molding cells that operate around the clock.
Duo H Application Areas
Duo H machines are ideal for a wide range of industrial sectors:
✔ Automotive structural parts
✔ Logistics & storage containers
✔ Industrial housings and casings
✔ Large packaging and bins
✔ Construction & infrastructure components
✔ Heavy-duty consumer plastic products
