Servo Controller Part:
1. High Precise Control
The servo system can control the machine's pressure, speed & location precisely, make sure that the error of accurate repeatability precision for the shot measurement is <0.3%
2. High sensitive response
Because the motor vector is matched with the controller accurately, it only takes 0.5sec. inputing the number from 0 to max. Compared with other traditional hydraulic injection molding machine, AF series is more faster in speed with shorter cycle time and high efficient in production
 
3. Energy Saving
Overall efficiency is 10% more & driving capacity is 18% more than common machine. This series can save 30-80% energy, and achieve first-class energy efficency
