Reduction of Shrinkage-Porosity Defects in Sand Casting Using Finite Element Analysis: A Review

Abstract

Today production of casting is easy but market requirement is quality casting. Earlier casting is made with large no. of defects due to large no. of process parameter in casting process. Specially, to predict phase transformation is very critical. As the problem of automation in process, shortage of skill labour now a days; casting simulation requirement is high and it is identifies defects earlier without making actual casting. This process reduces time and cost. Many casting defects occur like; hot tears shrinkage-porosity etc. at the time of solidification of casting. Casting simulation software is very much helpful to get quality casting. This paper reviews the details of solidification of castings in foundries using computer simulation. In this review paper study is done to reduce shrinkage porosity defects in sand casting component.
