Abstract
Supporting environmentally-conscious design of moulds is the ultimate objective of the here presented advisory tool. Relying on a careful estimation of the energy used for the injection moulding process, the designer is guided towards the development of green(er) solutions. As shown by literature and through a preliminary LCA screening analysis, most of the environmental impacts of a mould are directly connected to the energy consumed during the injection phase. This paper proposes a guideline for a reliable and sensitive energy estimation of the injection moulding process, taking into account not only the part and the material to be moulded, but also the specifications of the mould, the injection moulding machine and the injection moulding process parameters. The accurate estimation of the energy consumed may radically improve the estimation of the overall environmental impacts of the mould and of the moulded product, and provide a value-added support for eco-driven decision making since the mould design phase. This work aims at contributing to the development of new methodologies to help injection moulding industry to develop more sustainable parts, moulds and processes.
