Formation and Control of Defects in Iron Castings

Deepak Kumar, Manu Khare

Abstract :

Casting, one of the oldest manufacturing processes, dates back to 4000 B.C. when copper arrowheads were made. Casting processes basically involve the introduction of a molten metal into a mold cavity, where upon solidification, the metal takes on the shape of the mold cavity. Simple and complicated shapes can be made from any metal that can be melted.  The objective of this paper is to examine the metallurgical defects which have been found during examination of grey iron castings used to manufacture automotive parts using sand casting This paper examines some of the causes and cures. The defects type examined are shrinkage and gas defects such as pin and blow holes
