| Abstract Scope |
High-pressure die casting (HPDC) is an efficient manufacturing process suitable for automotive structural applications and for producing large components, known as mega- or giga-castings. In such large, thin-walled aluminium castings, the melt must travel long distances (meters range), making fluidity/melt flow assessment critical for ensuring proper filling and achieving the required mechanical performance. In this study, the fluidity of HPDC alloys AlSi4MnMg, AlSi7MnMg and AlSi10MnMg was evaluated using a serpentine (snake-like)-type mould under varying melt temperatures and gate speeds. The fluidity was assessed by means of melt flow distance, tensile properties at different flow lengths, microstructure examination and flow behaviour simulations using MAGMASOFT. The results show a clear difference in the melt flow lengths between the alloys and provide an understanding of the relationship between alloy composition, melt flow length, tensile performance and microstructural features. Furthermore, the findings demonstrate a potential approach for evaluating the fluidity of different HPDC alloys. |
