Abstract

In the changing global scenario, the foundry industries need to be environmentally friendly and to perform efficiently by reducing the number of rejections and should ensure quality products delivered. Some foundry industries are working with trial-and-error method and also undertaking research activities to ensure maximum output. Small scale industries found difficulty in undertaking research activities due to economic constraint. Large industries should transfer technologies to small foundry industries and further development can be made. The demand for defect free castings with minimum costs is increasing. This study is aimed to review the research made by several researchers in the field of reducing casting defects using FMEA, six sigma, quality control tools, Taguchi technique method and improve the casting process both qualitatively and quantitatively.
