Duo H Two Platen Injection Moulding Machine
The DUO machines are suitable for large-size parts. Thanks to the careful design and the customization with special equipment, the DUO model is particularly successful in the production of large-size items for the automotive industry, design, furniture and lighting.
The injection movement, hydraulically operated, develops considerable power appropriate to the size of the machine, with very high speed.
Screw rotation is operated by a brushless type, water-cooled electric motor, that controls a parallel shaft gear reducer of high construction, thus reducing pressure losses and noise to a minimum. The high torque generated allows high plasticizing capacities of all plastic materials processed including “hard” types. The drive command enables to use only the energy required by the plasticizing screw during the dosing process and to overlap the movement.
Heavy duty, compact two-platen clamp system, for fast mould changes through the automatic mould height adjustment function. The hydraulic control system is operated by a servo pump that controls and modulates the movement for high energy savings until the complete shutdown of the motor when the movement is finished. The tie bars, guided both front and rear and independent of the moving platen stroke, ensure precision of movement and fast locking action. The locking nuts are embedded in the fixed platen to guarantee high reliability during the locking action and to keep the operating area clear.
Accumulator for injection…..
An internal gear pump located under the injection unit, is driven by a very small electric motor and provides recharging of the accumulators. The accumulators act as “energy dam” once the required filling level has been reached the motor shuts off to minimize power consumption. The motor is controlled by a dedicated inverter thus maximizing the efficiency of the system.
