The El-Exis sets tomorrow‘s standards of precision and speed. Extremely fast travel and injection cycles are easily achieved without sacrificing in precision and safety. For thin-walled and packaging parts with minimum tolerances, as well as, for fast-cycling and precision applications employing high injection pressures, and in each clamping force range from 1,000 to 7,000 kN. Integral to achieving this is the unique combination of electric and hydraulic drives. Independent control loops operating in parallel for the clamping unit, injection unit and secondary movements, allow the El-Exis to realise extremely fast, harmonic and consistent movement cycles. The speed and response required for high-precision, fast-cycling parts during plasticising and injection are generated by the El-Exis at two levels. Firstly, the frequency-controlled electrical screw drive is the energy

Source with a high stored energy driving the rotary movements of the screw. The AC-servomotor transmits power practically loss-free to the screw. This design minimises maintenance requirements while ensuring quiet and energy-efficient operation. Its decisive advantage: plasticising is possible over almost the entire machine cycle, cycle time is shortened, and output, melt homogeneity, and quality of colour dispersion are higher. Secondly, high speed of injection is achieved by a hydraulic accumulator and a servo-valve. The result: the dynamic response of the linear movement is not compromised, neither during acceleration nor in applying the force by mechanical transmission elements. In effect, with injection speeds of up to 1,000 mm/s and a screw acceleration of up to 12 m/s² the machine achieves absolute maximum values.
