Sumitomo( SHI) Demag’ s advanced electric direct drive technology featured on the IntElect and PAC-E series has a huge impact on efficiency and machine reliability.
highest performing machines with all electric drives can reduce energy consumption by over 80 % compared to hydraulic technology. Additionally, the evolution of technologies now means that electric drives are increasingly viable for processing faster applications including caps and closures, as well as heavier loads such as automotive parts.
But even here, electric drive variants can and do vary. For example, an all-electric direct drive can be very different to a belt drive electric axis. A belt drive for example will typically couple the servo motor to the axis via a belt and ball screw assembly. Although noisy( from rotational velocity) and more complex to control, its relatively low mass and low inertia support quick and precise changes.
Conversely, an all-electric direct drive will couple the motor to

the ball screw controls. This is especially important for controlling platen stiffness. These drives adapt especially well to velocity changes, with little overshoot. Marginally more energy efficient(~ 4-5 %) than belt / gear systems, all-electric direct drives can also perform several tasks simultaneously in parallel operation.

Unlike other engineering companies, Sumitomo( SHI) Demag is the only known global firm in this field to design and manufacture its own drive motors entirely inhouse. This means that all drives are tailored to meet the unique operational demands of injection moulding machines.
From the perspective of relative efficiency, this integrated process plays a significant role in improving operational performance, expanding production capacity and further advancing energy efficiency. www. sumitomo-shi-demag. co. uk
