BP25 - HES for pressing machine

Address: District 6, Ho Chi Minh City
Project Summary: A plastic manufacturer in Ho Chi Minh City has installed HES sets for the injection molding machines to reduce power consumption.
Year of implementation: 2018

Status before implementation

The power consumption of the factory's existing injection molding machines:

- Hydraulic systems: 75 - 80%

- Ring heater systems: 10 - 15%

- Cooling systems: 5 - 10%

- Control Systems: 1 - 5%

HES sets should be considered to be installed to save up to 75% in power consumption:

Saving potential

Result

The factory has installed HES set for the injection molding machines, with the control principle as follows:

Images after installation:

After adopting the solution, the power consumption of the machine has decreased to 75 kWh/8 hours (from 285 kWh/8 hours before adoption). Oil temperature has reduced to 370 C..
