Core Advantages
European Pure Two-Platen Clamping Unit
European pure two-platen clamping design with non-contact tie bars, combined with independent tie-bar position adjustment and a mechanically synchronized brake mechanism, ensures reliable brake engagement and release and stable high-pressure clamping operation.
More Compact Overall Layout
Compared with conventional toggle machines, the parameter design delivers a smaller overall machine footprint together with greater tie-bar clearance, longer mold-opening stroke, and longer ejector stroke—well suited to deep-cavity and oversized molds.
Stable Floor-Standing Injection Unit
One-piece floor-standing injection unit design with a dual-cylinder nozzle-movement structure delivers stable injection performance and maintains injection accuracy under sustained heavy-duty operation.
Closed-Loop PM Servo Pump Hydraulics
A closed-loop permanent-magnet servo pump system delivers precise and stable control with excellent energy-saving performance, balancing high-response motion capability with energy efficiency.
KEBA Imported Controller
The electrical and control system uses a high-end imported KEBA controller for accurate, stable, and reliable control, ensuring process consistency on high-tonnage machines under high-pressure clamping and high-speed injection conditions.
Gen-2 Upgrade 6,500–40,000 kN
The DUII series covers the full clamping-force range from 6,500 kN to 40,000 kN with specialized and customized product services, matching applications from medium-large home appliance parts to extra-large industrial products.
