Influence of Piston Slow Shot Speed Variation in Shot Sleeve on Melt Flow, Solidification and Defects Formation in HPDC Process: a Numerical Modelling Study
Authors: , ,
Abstract: In this paper, the high pressure die casting (HPDC) process for Al-Si alloy is modelled with finite element method in ProCAST platform. The shot sleeve filling and die filling processes are described based on actual process parameters from HPDC machine. Three sets of piston slow shot curves are used to study its influence on free surface evolution and defects formation in final casting. According to final distribution uniformness of entrained air and oxides, the optimum piston slow shot profile is determined and can be further transferred into process control of actual HPDC process
