Low carbon manufacturing is a sustainable manufacturing idea based on ecological and environmental protection. For the manufacturing industry, it is necessary to comprehensively consider the resource consumption and environmental impact of the whole manufacturing life cycle, in order to reduce the resource consumption in the manufacturing process, improve energy utilization and minimize pollution emissions through manufacturing technology innovation. At present, the research on Moldless sand casting mainly focuses on the mold and the formability of castings, which is still in the stage of theoretical exploration, and lacks objective evaluation dimensions and methods in terms of sustainability.
Therefore, according to the characteristics of Moldless sand casting process, the low-carbon modeling of Moldless sand casting process is carried out by comprehensively considering the low-carbon indicators such as resource consumption, energy consumption and environmental impact. Among them, the establishment of resource consumption demand model is based on the above resource demand factors, and the carbon emission of casting process is used as the evaluation index of environmental impact.
Combined with the analysis of the characteristics of the dieless casting process, the resource consumption demand model, energy consumption and energy efficiency ratio calculation model, carbon emission and carbon efficiency calculation model of the dieless sand casting process are established, which can realize the quantitative calculation of the impact on resources, energy consumption and environment in the dieless sand casting process.
