Sand Casting Process Optimization via Design of Experiments: A Review

Abstract

Designing and optimizing of gating is an essential part of casting foundry as it contributes significantly to predict and minimize the flow turbulence resulting to casting defects like rough surface, sand inclusion, etc. An Optimization scheme for gating design parameters for casting was proposed with different past studies of the researches. Various designs were modeled and mould filling simulation rooted to minimize turbulence and macro defects are recommended in this review. Statistical software is introduced following the design of experiments (DOEs) practice, ‘Taguchi Method’ for optimizing designs. Results are analyzed through various mathematical methods showing the best combination of the parameters. Design of experiments for optimizing in gating systems is effective, easy to implement and bring out good quality casting.
