Parametric analysis of mould sand properties for flange coupling casting

In this research, the analysis of ramming factor, wall thickness, and quantity additives powder have been considered on permeability mould which is used to make flange coupling cast. The data has collected from sand making industry using L27 orthogonal array. It was revealed that maximum obtained lowest thin minimum mixing additives. number increased significantly proper allowability gas cavity. surface finish outer casting had improved with backpressure formation by increasing number. confirmation tests were conducted validate predicted process parameter responses.
