Parametric appraisal of strength & hardness of resin compacted sand castings using hybrid Taguchi-WASPAS-Material Generation Algorithm

Abstract

When compared to green sand moulds, resin bound sand moulds and cores have higher mechanical characteristics and create more dimensionally exact castings, and are thus increasingly preferred for near net form metal components. The effect of binder %, sand particle size and curing time on the mechanical characteristics of no-bake resin bonded mould core was studied in this study using lab testing. Their mechanical characteristics were discovered to rise with the addition of binder amount and curing time, along with dropping with increasing grain fineness number. Microscopic study of cross-linked resin bridges between sand grains also supports this. To get the best blend of mould characteristics, the results were optimized using the WASPAS technique and the Material Generation Algorithm. Tests were used to successfully validate the model and its findings. This study lays the groundwork for optimizing the moulding parameters of resin reinforced sand mould cores in order to achieve the best quality.
