Description
Low Pressure Die Casting (LPDC) is a widely used process for the manufacturing of automotive components. These components have high mechanical requirements, which
are difficult to achieve reproducibly within standard boundary conditions in LPDC. To ensure part feasibility, some areas are oversized to improve filling behavior and therefore local me-
chanical 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 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 reduced local
dendritic porosity, resulting in improved ultimate tensile strength and elongation values in an AlSi7Mg0.3 alloy.
