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

Parametric analysis of mould sand properties for flange coupling casting

The casting process is widely used because it has the advantage of being able to make products with small dimensions to very large dimensions, the use of materials is more efficient, the casting products can be directly used. However, in the casting process, the main triggers for the formation of defects are the nature of the mold, low permeability, low molding compressive strength, low sintering point, unsuitable sand grain distribution, so research is needed to obtain the right type of molding sand as a sand mold in metal casting. The only type of additive is bentonite. Bentonite can absorb water and expands between 8-15 times and remains dispersed in water for a certain period of time. This study aims to examine the effect of a mixture of variations of local bentonite and Australian bentonite on the characteristics of the molding sand for the sand casting process. The tests carried out are in the form of size distribution testing, X-Ray Diffraction, water content testing, compressive strength, and permeability measurements. Bentonite was varied into 5 variations of the mixture with a difference of 20% in each mixture. The results of the large size distribution of silica sand grains were 37.6 GFN. The results of XRD testing of local bentonite showed a higher content of calcium compounds and Australian bentonite contained higher sodium compounds. The largest water content test value is 5.825%. The largest compressive strength test value is 2.7 Kgf /cm 2 .
