Hybrid injection molding machine
HIGH PERFORMANCE AND ENERGY SAVING
Available in the range from 50 to 800 tons, Multipower is based on a mixed technology of drives, hydraulic and electric systems, targeted to provide maximum performance with minimum power consumption.
INJECTION AXIS AND ACCUMULATORS
The injection movement is based on a rotary piston, hydraulically balanced under accumulators without any thrust bearings. This is the most complex movement of the machine and it determines the quality of the moulded product.
A servo valve (Moog) provides closed loop control of speed, pressure and backpressure thus ensuring optimal conditions even for the more sophisticated mouldings. A pump located under the injection unit, with internal gear driven by an electric motor of a very small size, provides for the recharge of the accumulators. Once the required level has been reached, the motors shuts off to minimize power consumption. Switching on/off is controlled by inverter, thus maximizing the efficiency of the system.
This procedure allows to obtain speed performance otherwise impossible and a control of a hold-on pressure extremely precise and adjustable according to the characteristics of the moulded product, reducing at the same time consumption of energy. Therefore the advantages of this application are: reliability, high performance, high precision and energy savings.
