This technical paper reports on a collaborative project with Sydow-Druckguss GmbH and two other organizations using simulation methods to assess and optimize process efficiency and enhance product quality early in the design process. In this project, Altair® Inspire™ Cast simulations successfully demonstrated the feasibility of using High-pressure die casting (HPDC) for actuator housing production. The comparison between the simulations and X-ray results from casting trials showed a high level of agreement, confirming the accuracy and reliability of Inspire Cast. This successful endeavor validates Inspire Cast as a high-precision casting simulation tool for the HPDC process.
