Abstract

The preferred method for producing lightweight metal components, mainly from aluminum and magnesium alloys, is through high pressure die casting. This process involves rapidly and forcibly injecting liquid metal into a metal mold under high pressure. Our study aims to compare results obtained from the numerical modelling of the filling of aluminum under high pressure with the experimental results. Two different cylindrical pipes are used. The results indicate for imposed values of KE = 14 and KW = 60 for pipe 1(Dentry/Drp=40/40) and pipe 2 (Dentry/Drp=16/40) respectively, the mathematical model with the same initial conditions gives some results which are close to the experimental data. The results also indicate that pipe 2 is damped faster than pipe and this is due to the singular pressure loss at the entry.
