Analysis and Optimisation of High Pressure Die Casting Parameters to Achieve Six Sigma Quality Product Using Numerical Simulation Approach

Suraj R. Marathe Assam Don Bosco University, Carmo E. Quadros Assam Don Bosco UniversityDate Written: February 13, 2021 Abstract A numerical simulation approach is proposed to predict the optimal parameter setting during high pressure die casting. The contribution from the optimal parameters, the temperature, showed more influence on the casting quality than the other parameters.
