SE-HDZ Injection Unit Features
The mid-sized SE-HDZ all-electric injection molding machine uses two Sumitomo-built AC servo motors with full closed-loop control and digital sensors for the injection unit. Developed for high-duty applications, the SE-HDZ’s injection motor provides the ability to consistently maintain very high hold pressure for an extended period of time.
Working together with the new Z Control, the SE-HDZ delivers improved precision with low-pressure filling. The Z's patent-pending Flow Front Control (FFC) System optimizes the flow front, further allowing control of low internal pressures inside the cavities. This system:
Another aspect of the SE-HDZ is the increased injection capacity for large molded products. On the SE280HDZ, for example, the injection capacity ranges up to 76.1 in3.
Other advantages of the SE-HDZ Series injection unit include:
Additionally, with the SE-HDZ Series, Sumitomo’s extensive experience in designing and manufacturing electric motors ensures that each machine configuration has the absolute best combination of motors to ensure superior performance (the right amount of torque) while keeping the machine reasonably sized and priced.
The SE220HDZ, for example, employs Sumitomo direct-drive motor technology for injection and screw rotation, regardless of injection unit chosen. The SE450HD is equipped with high-capacity belted motors and the motor for injection uses two, large-load capacity ball screws to ensure highly efficient power transmission and outstanding durability compared to single screw motors. (Consult your Sumitomo representative for the exact combination of motors for the particular tonnage and injection unit size selected.)
