Among the industrial activities and casting process still remains as one of them ost complex and indefinite activities. Due to the complex relationship between casting defects and greens and properties, it is imperative to control many greens and characteristics that influence casting quality. Traditional method of trial-and-error based on know-how and experience has many disadvantages such as being nonsystematic, time consuming, error-prone and requirement for long durations of experimentation. There is a necessity to replace this traditional approach to produce higher quality casting products within reasonable periods of time making better use of statistics, artificial intelligence knowledge acquisition neural networks and data mining tools. This paper extensively reviews published research on greens and casting process. The effect so friser design, gating system, mouldings and, oxidation and distortion of casting all through heat treatment, machining all owance, etc., on the economical manufacture quality castings were reviewed. Determining the optimal process parameter setting will significantly improve them would yield, out put ratio of metal, shorten manufacturing period, save energy and resource, reduce pollution, and improve the competitiveness of enterprises
