Abstract

Sand casting is a versatile and common used manufacturing process in metal casting industry. This method can be used in almost all types of metal and the sand is recyclable. However the defects in casting product such as blowholes, pinholes, shrinkage and porosity cause imperfection in green sand mould. The aim of this project is to optimize the composition of silica sand, bentonite, water and coal dust in green sand to reduce the defects in the casting products using 24 factorial experiment design method. The effect of composition of green sand on permeability, green compression strength, and shear strength was investigated. Analysis of Design Expert software identified that bentonite and water are the main interaction effect in all the experiments. The optimal settings for green sand composition are 100g silica sand, 21g bentonite, 6.5g water and 6g coal dust, whereby the ratio of their weight contents in a 150g green sand is 68: 14: 4: 4; this composition has an effect of permeability number 598.3 GP, compression strength 26kN/m2 and 20 kN/m2 for shear strength.
