Numerical Simulation of LPDC Process for Thin-Walled Aluminum Alloy

Abstract:

In general, the thin-walled casting with the thickness less than 2mm is not easy to be prepared using low-pressure die casting (LPDC) technology because of its poor filling-ability. In this paper, the LPDC process of A356 thin-walled aluminum alloy was simulated based on the selection of appropriate boundary conditions in order to save the cost. The simulation results compared with experimental results indicate the numerical simulation technology is an effective tool for reducing the manufacturing cost and improving the casting quality.
