1. Power saving: The servo motor injection molding machine changes according to the needs. Unlike the three-phase AC asynchronous motor, the speed and torque are constant. The motor torque speed = X output power, so as to achieve the effect of power saving, which is very obvious. In addition, the magnetic field in the servo motor is generated by strong magnetic materials; the magnetic field of the AC asynchronous motor is alternating current, which is generated by the stator of the motor and consumes energy (estimated to be about 10%). Therefore, power saving is the characteristic of servo injection molding machine；
2. Precision: Since the servo injection molding machine adopts a pressure sensor, the pressure sensor continuously feeds back signals, and the control system performs real-time control so that the pressure and flow of each stage can be realized quickly and accurately. Realize double closed-loop control. Improve product repeatability. The traditional injection molding machine is open-loop control, and the accuracy is much lower.
3. High efficiency: Due to the fast response speed of the servo motor, it only takes +0.5 milliseconds from 0 to the rated speed, so the efficiency of the processed product is increased by about 2%.
The injection molding machine is the main production equipment in the plastics industry, and the waste of electricity is serious. Due to the high price of electricity, electricity accounts for a considerable proportion of the production cost of enterprises, which has become an important factor that seriously affects the production efficiency of enterprises.
With the intensification of market competition, enterprises have taken measures to save energy, reduce consumption, and reduce production costs, thereby improving market competition, and customizing products according to motor power, injection molding machine users' motor speed, pump displacement, and pressure system to meet all specifications of the equipment.
The servo installation process is the same as that of ordinary machines, which is convenient and simple and is well received by enterprises in the plastics industry. The products are beautiful, durable, power-saving, and environmentally friendly. According to different injection products, the power saving rate is 35%-80%. The total investment recovery period is 6-12 months, and it is the most ideal product for the energy-saving transformation of injection molding machines.
