A Review on Casting Defects Analysis for Optimization of Process Parameters to Minimize Casting Defects

In today's age of globalization, foundry plays basic and versatile role in manufacturing industries. The high effective performance of foundry industry is determined by its minimum number of rejections in casting and achieving better result at minimum cost. The industries face problems like poor quality and low productivity due to constant rejection of casting components for which uncontrolled parameters or lack of skilled workers or low penetration of automation is responsible. The casting defects in industries do not occur without any disturbances in casting operations. It is due to the slight changes in execution of casting process which affects the process parameters. The defect free casting with minimum rejection and high quality at low cost is the need of time. This can be achieved by application of simulation, achieving proper gating and risering design, controlling of process parameters and standardization of casting operations. This paper is aimed to collect the reviews of researchers and explain the need to carry out casting operation in order, to improve the productivity of industry.
