Optimization approach for evaluation ofmechanical properties and process parameters of Aluminum high pressure die cast product:- Ekpendu Prince

ABSTRACT

This project work produces a machine component using a high pressure cold chamber die casting machine. The chemical compositions of the aluminum cable coil were 10%wt silicon and 0.6%wt of magnesium and 0.5%wt of copper while the aluminum coil contains 97.82% aluminum. 1.17% of silicon, 0.54% of copper 0.35% magnesium, and traces of iron and chromium. Taguchi method was adopted for optimization ofthe process and response parameters to obtain the optimum performance of porosity using density as response factor.The optimal value was obtain with sample specimen 3 with charging masses of Si = 0.7; Cu = 0.8 and Mg — 0.7 with density of 2.7533 and porosity = 0.3632 while at this optimal value, the following response parameter values were obtained: impact = 136/416 Joules; UTS = 58.487 N/mm2; Hardness = 41 HRB, %Elongation = 11.3649; Y.M = 882.3998; Flexural Strength = 105.9556 N/mm2 with a yield strength of2.0763 N/mm2.
