NADCA: For Efficient Manufacturing, Look to Die Casting
A concise outline of the specific facts regarding how die casting manufacturing efficiency contributes to ecological sustainability: All die casting metals can be recycled and reused with no loss in material properties, resulting in the vast majority of die castings made with post-consumer metals which, in addition, require far less energy to reprocess than virgin materials. In the production of non-ferrous metal castings, die casting is the most energy-efficient casting process, with reusable molds and very high production rates resulting in highly-efficient energy usage. The carbon footprint of the die casting industry is among the lowest among producers of net- or near-net shape products and component parts—far less than that of plastic injection moldings.
