Servo-pump injection molding machine for thermoplastics
The hydraulic system is based on the use of a servo pump designed with the aim of promoting significant energy savings (Hybrid Energy Saving). The hydraulic system of this machine is extremely simple and reduced to essential thus ensuring high reliability in time and easy maintenance. A servo motor drives a high performance gear pump. The whole system is controlled by a drive (inverter) with a dedicated software that allows a rotation speed of the motor from 0 to 3000 revolutions / minute with an extremely high acceleration gradient.
The system can also read the output pressure generated and control the motor so as to maintain the pressure exactly at the set value. This combination of P / Q control and the exceptional high dynamics of the motor generates the power necessary to the real performance of the machine without introducing the well-known pressure losses of the traditional hydraulic systems. This technology allows measurable energy savings between 30% and 60% and, most important, the limited quantity of oil in the hydraulic line is not subject to overheating.
The cooling system, of reduced dimensions, is activated only when necessary.
Not least, the noise of the system remains below 60 db.
