There are four main energy consuming units in an injection mould machine, there are hydraulic pumps, heating unit, cooling system and control components. Among these the hydraulic power consumes the most energy, approximately 75% of the machine's total energy consumption.
The motor of the hydraulic pump runs at fixed speed (50Hz) and provide equal amount of pressure and flow, while theamounts of pressure and flow required for each stage of clamping, injection, pressure holding, cooling and ejection are all different, hence it accounts for large energy lost. There is an overflow valve to adjust the excessive pressure and flow at each stage, but this method doesn't practical enough in the goals of energy saving. The Hybrid Energy System (HES) is developed to address this problem.
