| Abstract Scope |
This study investigates the influence of casting parameters on the performance of a semi-solid casting technology utilizing a vacuum dosing unit to produce high-quality components. In this process, the melt is conditioned directly in the dosing container using electromagnetic stirring in an inline conditioning station integrated into the HPDC machine. To evaluate the effectiveness of this approach compared to conventional HPDC, casting trials were conducted in industrial environment. The impact of process parameters, particularly the shot curve and die temperature, on casting quality and mechanical performance was systematically evaluated. Structural integrity and mechanical properties of the cast components were assessed through X-ray inspections, microstructural analysis, and tensile testing. The results indicate that elevated die temperatures and earlier switchover points significantly enhance casting quality. Components produced via this semi-solid process exhibited improved structural integrity, with a notable reduction in porosity, primarily attributed to decreased air and oxide entrapment during die filling. These findings highlight the potential of the semi-solid casting technology to mitigate defect formation compared to conventional high-pressure die casting. |
