Servo pump Multipower SP

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.

The Five movements

INJECTION UNIT

The injection movement is based on a rotary piston, hydraulically balanced without thrust bearings. This is the most complex movement of the machine and determines the quality of the final product. The axis control, entrusted to a servo valve (Moog) in close loop control of speed, pressure and back-pressure, ensures the optimization of all the conditions required even in the most sophisticated moulding processes.

PLASTICIZATION

The rotation movement of the screw is operated by hydraulic motor directly connected. The high torque that characterizes these motors allows the plasticization of all the technical and “hard” thermoplastic materials. The servo pump, at this stage, generates the flow rate and the ideal pressure for the screw rotation thus allowing considerable energy saving.

CARRIAGE AXIS

The injection movement is performed by two hydraulic cylinders which allow the unit to maintain its position thus reducing energy consumption to virtually zero. Once the system has been loaded, a non-return valve prevents the emptying of the cylinders.

CLAMP UNIT

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 opening/closing movement is actuated by a hydraulic piston that ensures reliability of the system. The movable platen is supported by adjustable sliding blocks that ensure complete safety of the mould.

CENTRAL EJECTION

The central ejection is actuated by a hydraulic drive, allowing a considerable ejection force and long strokes as well as high flexibility when hooking-up the ejection rods of the mould.

Optimized with three working modes

A SMART SOFTWARE

An operator interface mixed with video touch and push buttons for manual operation allows a user friendly man-machine interface in a simple and intuitive way.
