Identification and Analysis of Casting Defects

Abstract

Casting process is the most widely used process in manufacturing industries. Production of casting involves various processes like pattern making, molding, and core making and melting. It is very difficult to produce defect free castings. Systematic analysis and identification of sources of product defects are essential for successful manufacturing. Since the quality of casting parts are mostly influenced by process conditions, how to determine the optimum process condition becomes the key to improving part quality. The industry generally tries to eliminate the defects by trial and error method. This paper describes the identification and analysis of the casting defects. Filling related defects, Shape related defects and Thermal related defects of casting products are discussed in this paper. Defects occurred by various gating system parameters are also be identified. So good gating system reduces the defects.
