The Daoben EV Hybrid series injection molding machine combines a servo-electric injection drive with a hydraulic clamping unit. This hybrid design accelerates injection response speed and improves shot precision — fully meeting high-precision manufacturing requirements for ultra-thin and precision parts. A full-hard chromeplate screw and bi-metallic barrel deliver outstanding wear resistance and a longer service life. Five models cover a clamping force range from 90 to 268 tons, with injection speeds up to 440 mm/s and injection pressure up to 300 MPa.

The same base components can be freely combined with different specification injection parts. Each tonnage model can be configured with large, medium, or small injection units.
Injection components are optimized to accelerate injection speed and enhance response efficiency. Injection speeds reach up to 440 mm/s on EV90 through EV170 models, fully meeting customers’ high-precision manufacturing requirements for ultra-thin and precision parts.
Low-inertia injection component design is matched with a high-power full-electric servo motor — the same motor type used on all-electric machines.
The EV Hybrid clamping unit is equipped with a high-precision clamping proportional valve. Positioning accuracy reaches 0.2 mm, giving repeatable mold-close position throughout the production run.
Five standard models cover a clamping force range from 900 kN (EV90) to 2680 kN (EV268). Mold opening stroke ranges from 320 mm on the EV90 to 560 mm on the EV268.
Minimum to maximum mold thickness is programmable and covers 150–350 mm on the EV90 through 220–600 mm on the EV268. The ejector system delivers 31 kN to 77 kN ejector tonnage depending on model.
Conventional injection machine controllers run a control cycle of 3–4 ms. SDC reduces this to just 0.120 ms — a reduction of up to 32×.
The SDC algorithm is proprietary to DAOBEN and resides inside the servo driver hardware itself — not in a separate PLC or motion controller. This means the drive calculates corrections locally, in real time, without waiting for a command from an external controller.
SDC improves control position accuracy across three key machine axes: injection position, mold-open position, and mold-close switching position.
The EV Hybrid uses a high-performance control platform co-effective with the ETHERCAT CAN-bus system. This offers high-efficiency anti-jamming performance and high-speed internal calculation, guaranteeing real-time bulk data transfer and precise process control across all machine axes.
Closed-loop control manages injection speed, hold pressure, screw position, and back pressure independently. The ETHERCAT bus eliminates signal delay between the controller and servo drives
The controller maintains process stability across extended shifts. Shot-to-shot variation is minimised, keeping part quality consistent from the first cycle to the last.
Precision for Ultra-Thin Parts: Injection speed up to 440 mm/s and injection pressure up to 300 MPa meet the tightest demands of thin-wall and precision part manufacturing. Low-inertia servo injection responds instantly — reducing fill imbalance, short shots, and flash.
Longer Equipment Life: Full-hard chromeplate screw and bi-metallic barrel are standard on every model. This significantly increases screw and barrel service life compared to standard configurations, lowering replacement cost and reducing unplanned maintenance stoppages.
Modular Flexibility: Three injection unit sizes available per machine tonnage — large, medium, and small. You can configure exact shot volume for each application without changing the machine frame. One machine covers multiple product families and resin types.
Positioning Accuracy to 0.2 mm: High-precision clamping proportional valve delivers mold-close positioning accuracy to 0.2 mm. Consistent mold-close position protects tooling parting surfaces, extends mold life, and maintains part dimensional consistency across the full production run.
The EV Hybrid series is designed for manufacturers who need fast injection response, high dimensional precision, and durable equipment for high-volume production. Ideal industries and application types include:
