Warpage in casting: A Review

Abstract

Foundry industries in developing countries suffer from poor quality and productivity due to involvement of number of
process parameter. Even in completely controlled process, defect in casting are observed and hence casting process is also
known as process of uncertainty which challenges explanation about the cause of casting defects. In order to reduce warpage
defects and problem related to warpage defects, the study is aimed in this paper. Many products are made by using casting
process as it is economical and has the ability to produce intricate shapes. So far, casting defect analysis has been carried out
using techniques like finite element method and modulus method to reduce defects. . Casting software can optimize the virtual
castings so that real castings can be produced ‘right first time and every time’.
