  • Page 3: Energy Saving Principle

    Energy Saving Principle For traditional injection molding machines with constant delivery pumps, valve adjustment is required to change load flow rate and pressure. In this case, input power changes slightly, and a large proportion of energy is consumed by the valve in the form of pressure difference, causing overflow.
