Precision investment casting of aluminium machine parts using specially designed ceramic mould

Abstract

jlsvestment casting process is a well established manufacturing process with greater product design feedom from very simple to highly complex parts with tight dimensional tolerances and excellent = surface finish compared to ther casting processes. Therefore expensive machining, wastage of insaterial could be reduced or eliminated while providing more design economy and flexibility than pother casting process.: The investment casting is widely used for producing complex geometries of ferrous and non ferrous . materials [1]. Many researches have been performed on this subject during past four to five decades. 'The ancient method of investment ("lost wax") casting of metal components has been transformed asto a near net shape forming technique offering jt the designer at the forefront of metal casting, .'economy and flexibility [2]
