Detailed introduction: Introduction of the traditional conditions of injection molding machines: In the injection molding machine is carries on after all kinds of plastic the heating, melts the melt, the agitation, turbo-charged, the plastic fluid pours into the mold to file an accusation, completes a work piece injection molding the equipment.
Consuming energy: Matched molds. Mode locking. Shoots the rubber. Sol. Guarantees the pressure. Cooling. The die sinking and so on several stages need the different pressure and the current capacity, but the oil pump electrical machinery in the constant speed revolution, creates the energy waste. The craft is unreasonable: The different working procedure oil pump's rotational speed is the same, has not been able to real-time change electrical machinery rotational speed because of the technological requirement.
The work piece service life is short: The injection molding machine oil temperature is high. The noise is big. The service life of the machinery and the seal lessens under the most tremendous pressure and the current capacity.
The electrical machinery protection is insufficient: The electric motor frequent line start, the electric current is big, the life lessens, simultaneously bring big pollution to electrical network.

The main performance According to rapid starts and stops of the injection molding machine , the design of large over - flow multiples has greatly strengthened theovercurrent overload capacity of the motor; Asynchronous space vector PWM, Section steeples synchronous space vector PWM , two-phase optimization of the space vector PWM ; The output frequency and output current can be adjusted individually , output a perfect sinusoidal current waveform , the power factor above 0.95 ; Realize low frequency (1Hz) large output torque control under V / F control mode, automatic torque boost function ; Before the inverter starts automatically pursue the motor speed ; Using electricity / energy running into control mode in order to avoid affecting the normal production when break down ; 15 object of the operation monitoring , multi-angle dynamic monitoring machine operation. Application: all kinds of plastic extrusion equipment
