Life Cycle Analysis of Conventional Manufacturing Techniques: Sand Casting

A system-level environmental analysis of die casting based on aggregate national data and representative machine characteristics could be applied to design and manufacturing decisions where environmental impact is accounted for. By examining the life cycle of a process, it is possible to consider the environmental impact of the metal forming process as well as the impact of associated processes such as metal preparation and die preparation. The emphasis on aluminum high-pressure die casting reflects the current state of the industry and its environmental footprint. An energy analysis exposes the clear and significant environmental benefits of the use of secondary aluminum. Analysis of material byproducts gives less straightforward solutions, where improvement on one field comes at the cost of another
