HYBRID ESP Injection Molding Machines – Energy-Efficient Hybrid Injection Technology
The Plastic Metal HYBRID ESP series is developed to deliver high performance, low energy consumption and long-term production stability through advanced servo-pump driven hybrid injection technology. The system combines hydraulic power with the precision of electric control, ensuring optimal productivity across a wide range of industrial applications.
The HYBRID ESP platform incorporates servo-pump technology capable of reducing energy consumption by approximately 30% to 60% compared to conventional hydraulic machines. The motor operates only at the required power level and can stop completely during static phases of the production cycle, minimizing overall energy use.
Wide tonnage range and flexible production capacity
HYBRID ESP machines cover a broad production spectrum, from small precision parts to large technical components:
clamping force range from 50 to 3200 tons
490 to 31,390 kN clamping force options
mould opening strokes from 250 to 2200 mm
mould thickness range from 100 to 2200 mm
This structure provides maximum flexibility for different mould sizes and industrial production requirements.
High injection performance and production efficiency
The HYBRID ESP series stands out with high shot capacity and strong plasticizing performance:
shot volume from 22 cm³ up to 43,370 cm³
shot weight from 20 g up to 39 kg (PS equivalent)
injection speeds from 26 to 5000 cm³/sec
plasticizing capacity from 5.6 to 2500 kg/hour
This performance range supports both thin-wall packaging applications and thick-wall technical components with high efficiency.
Energy savings with servo-pump technology
The combination of a brushless servo motor and high-performance gear pump provides:
energy savings of up to 60%
automatic pressure and flow adjustment according to load demand
complete motor stop during idle phases
reduced heat generation and lower cooling requirements
This significantly lowers operating costs and supports sustainable manufacturing.
High precision and repeatable production
The machine integrates advanced components such as Moog servo valves, linear guide moving platens and a rotary piston injection system to ensure:
high injection accuracy
stable pressure and speed control
low vibration levels
excellent repeatability
ensuring consistent product quality in continuous production environments.
