The ALLROUNDER E (EDRIVE) machines are entry-level models into the world of ARBURG electric machines. They are particularly suitable for the effective production of technical parts. High precision and performance in combination with an attractive price make the series an economical electric alternative to hydraulic injection molding machines.

In the ALLROUNDER E machines, the main axes for injection, dosing, and mould opening and closing are servo-electrically driven as standard, and therefore fully independent from one another. Fast acceleration and final speeds, as well as simultaneous movements reduce cycle times, leading to high cost efficiency.

In our ALLROUNDER E machines, direct-acting play-free spindle drives ensure mechanically rigid drive axes and correspondingly dynamic movements. High-resolution, contactless position measurement by an absolute position encoder in the motor makes movement to a reference position unnecessary. The excellent positioning accuracy of all servo-electric drives permits maximum reproducibility and part quality.

The high efficiency of the servo-electric drives and the toggle-type clamping unit of the electric ALLROUNDER machines ensure energy-efficient operation. The energy recovery of the servo motors during braking also has a beneficial effect on the machines’ overall energy consumption. Together, these factors combine to reduce energy consumption by 25 to 50%. As an indication of their optimum energy efficiency in operation, all electrically driven machines bear the ARBURG “e²” energy-efficiency label.

The drives of the ALLROUNDER E machines are liquid-cooled and are therefore especially quiet. Air turbulence is avoided and the targeted dissipation of heat considerably reduces the amount emitted into the environment. Closed drives and spindle systems reliably prevent exposure to dust caused by abrasion. The machines are therefore perfect for clean room production of optical components, decorative parts, precision and micro components, for example.

A wide range of machining tasks can be accomplished with consistently high quality using the high-precision ALLROUNDER E machines. The high degree of reliability of the machines and subsequent minimal variability in the process is achieved by numerous technical details. These include the adaptive temperature control for stable process conditions and the closed cooling circuit for motors and converters for rapid cycles and long holding pressure phases.
