Even when idle, injection molding machines consume energy. The base load for standard (older) machines can range from 52% to 97.5% of the full molding energy consumption. For idle periods exceeding 20 to 45 minutes, it may be more cost-effective to switch off and restart the machine. At the very least, unnecessary services and functions, such as the main hydraulic motor, should be turned off to save energy.
