The SF81 injection molding machine servo drive is capable of double closed-loop control on pressure and speed, based on pressure and flow desired by different working conditions. Through pressure sensor, the servo control system reads the hydraulic circuit operational pressure and compares it with the pressure command from the host computer. Then, the system will automatically adjust the motor speed to complete the discharge of excess hydraulic oil without overflow valve. In this way, the energy is saved by 20% -60%. The servo drive is an ideal choice to accelerate investment return, as well as to improve injection efficiency and precision.

Voltage Rating of Injection Molding Machine Servo Drive
AC380V (three-phase power) 11 ~ 75KW

Features of Injection Molding Machine Servo Drive
1. Excellent Energy Conservation
In an ideal working condition, the energy saving rate can be 20%-60%, which excels the traditional hydraulic power control system.

2. Good Stability
The servo drive achieves precision closed-loop control of pressure and flow, and has greatly improved repeatability compared with conventional hydraulic control system.

3. Quick Dynamic Response
The servo control function is highly sensitive. The start or stop only takes about 0.1 second.

4. Large Load Capacity
A 3 times overload capacity ensures the stable operation of injection molding machine in frequent frequency fluctuation.

5. Multi-Channel Frequency Signal Input in Various Types
Proportional pressure signal and proportional flow signal are simultaneously accessible. The electrical signal source can be 0 ~ 1A / 0 ~ 5A, 0 ~ 10V / 0 ~ 5V, or 4 ~ 20MA / 0 ~ 20MA.

6. Rich Combination of Frequency Setting
The frequency can be given by the four types of combination of pressure signals and flow signals, which satisfies requirements of all the working conditions.

7. Quiet Operation
The servo drive has low noise during high carrier operation and is even quieter during low speed running. The noise is less than 70db under ideal conditions.

8. Reliable Pressure Maintaining
In closed-loop pressure control, the pressure maintaining can be more durable and more stable.

9. Double-Loop Design
The double-loop design of electricity supply and electricity conservation ensures continuous operation of the system, without affecting production.

10. Small Temperature Rise
During continuous running, the output of hydraulic oil is in proportion to avoid excess heat generation. Meanwhile, the hydraulic oil does not require cooling, to achieve significant water conservation.
