Benefits of frequency inverter (variable speed drive) for injection molding machine (part 3)
Continued from the article: Benefits of frequency inverter (variable speed drive) for injection molding machine (part 2).
Frequency inverter and the system controller are used for injection molding machine to only pump the oil needed. The system controller monitors the machine's controller and generates a signal that corresponds to the needed volume of hydraulic oil. Thus with these 2 equipments, if the machine does not need the oil, don't pump it in the first place.
The advantages of this system on injection molding machine include energy saving, better repeatability (it is easier for the machine to control the lower volume of oil), quieter machine operation, lower oil temperature, less demand on the cooling tower and less wear and tear on the machine.
Generally the AC drive (frequency inverter) system is a wise investment for a particular machine/mold/manufacturer combination. You will get those advantages we mentioned above.
Applying AC drive (frequency inverter) system is suitable for situations below:
1. Manufactures in areas with high electrical costs
2. Long cooling times
3. Large machines
4. Older machines
The final outcome of applications of frequency inverter (variable speed drive) for injection molding machine will be very positive.
