Die-casting fast energy storage and pressurized energy storage

Is die casting energy efficient?

Discussions Die casting is an energy-intensive process that has prompted energy efficiency evaluation toward achieving greener, more sustainable manufacturing processes. However, the complex production conditions require even higher real-time and dynamic performance of energy efficiency evaluation.

What is Overall Equipment Effectiveness (OEE) of die casting unit?

Overall equipment effectiveness (OEE) of die casting unit is the main indicator used in equipment management and energy efficiency evaluation and reflects the overall efficiency of equipment as well as the proportion of time or energy available to create value.

Does die casting workshop use a lot of energy?

The main results are as follows: 1) The OEE and energy utilization ratio of die casting units were increased by 3% and 7%, respectively; 2) Energy consumption per kilogram of die casting workshop was reduced by 7.9%. The proposed approach can be used to trace the source of energy inefficiencies in the die casting workshop.

What is die casting?

1. Introduction Die casting is a high-efficiency, near-net-shape forming process that has been widely used in some key areas of the national economy in China, such as the automobile, ship, aviation, and telecommunications industry. However, it is one of the most energy-intensive manufacturing processes [1 ].

What is energy consumption of die casting unit in power off and standby States?

The energy consumption of die casting unit in the power off and standby states are denoted Epo and Esb, respectively. The energy utilization ratio of the die casting unit uu and the energy consumption in the standby and power off states can be expressed as.

What is energy utilization rate in a die casting unit?

The energy utilization rate in each die casting unit is an essential index reflecting the energy management of the equipment. As the indicator increases, less energy is consumed by the equipment in the standby and power off state. The operation states of the die casting unit can be identified through big data analysis of electrical current data.
