ABSTRACT:
Nowadays, in the area of casting, the focus is on cost and resource efficient production of increasing complex shapes, miniature precision component along with the considering environmental issues, put an all stringent requirements on the advances in casting technology. Casting is the primary manufacturing process is being developed at each and every stages over centuries of years to satisfy the needs of the customer. This paper reviews most of the advanced casting techniques and their advantages, limitations and applications in the field of engineering. The paper is divided into four sections, the first section details about the casting process within expandable mold with expandable patterns such as investment casting, full mold process and replicast process. The second section describes about the semisolid process such as thixocasting, rheocasting and thixomolding. The third sections explains non-bonded sand molding process such as vacuum molding and magnetic molding and the fourth sections associates with the centrifugal casting process such as De Lavand process and Moore casting process.
