Abstract

Manufacturing industries are facing tough competition due to increasing raw material cost and depleting natural resources. There is great pressure on the industry to produce environmental friendly products using environmental friendly processes. A computer-aided system named Sustainability Assessor for Die-casting has been developed and presented in this work. The system can assess the sustainability performance of a die casting process plan. The system determines the CO2 emissions, solid waste, and energy use based on the process plan information. Two case studies for gravity die-casting and pressure die-casting are demonstrated the sustainability analysis based on system developed. The proposed system is verified by comparing results with the actual data measured from the shop floor. The developed system is beneficial for sustainability assessment comparing different plans alongside material properties, ultimately helping the die-casting industry to reduce the carbon emissions and material waste, besides improving energy efficiency. It is expected that this would be highly beneficial for determination of environmental impact of a process at early design stages. Therefore it would greatly help the manufacturing industry for selection of process plan based on sustainable indices. Overall impact of this study would have good impact on reducing air emissions and protecting environment
