Description
Summary:Low Pressure Die Casting (LPDC) is a widely used process for the manufacturing of autmotive components. These components have high mechanical requirements, which are difficult to achieve reproducibly within standard boundary conditions in LPDC. To ensure a part feasibility, some areas are oversized to improve the filling behavior and therefore the local mechanical properties. Targeting these issues of high mechanical requirements, an “active insert” has been developed, which actively influences the casting process using magneto hydraulics principles and therefore the part quality significantly. The process reliability due to porosity reduction was increased compared to the existing LPDC parts. For a characterization, tensile tests and microstructure analyses were carried out. It could be proven that the casted parts show an average grain size reduction, a more homogenous microstructure, and a reduced local dendritic porosity, resulting in improved ultimate tensile strength and elongation values in an AlSi7Mg0.3 alloy.
