Elettryka Electric Injection Moulding Machine
ELETTRYKA is an innovative range of “full electric” injection moulding machines in the range from 50 to 1000 tons. All movements are electrically operated. In addition to the usual characteristics such as strength reliability and advanced technology. Elettryka achieves a drastic reduction of energy consumption ensuring the best performance in terms of production efficiency and precision.
The injection unit is controlled through ball screws driven by brushless servomotor and allows exceptional precision of repeatability of the moulded parts. The control of hold-on pressure and back-pressure is ensured by the feed-back of the load cell of the system.
The screw rotation of the screw is operated by an electric motor. This high torque brushless motor allows the best performance of the movement ensuring optimization of the plasticizing process also for “hard” thermo polymers. The water cooled motor is operated by a drive that allows to use only the energy required for the screw charge. It also allows simultaneous movements.
The mechanical structure of the clamping unit is characterized by a 5-point double toggle with steel links and special bronze bushings and a multiple point lubrication system with programmable cycles and safety devices. The clamping movement is performed by an electromechanical axis that exploits a ball screw. The rotation of the system is provided by a brushless motor specially designed with a hollow shaft installed directly on axis.
The movement of the injection unit is performed by two ball screws driven by a brushless inverter-controlled motor.
The ejector is driven by two ball screws driven by a brushless motor allow to keep the central plate ejector area clear for easy access to the mould fitting.
