Casting Defect, Causes and Their Remedies A Review

Abstract

Foundry industries in developing countries suffer from poor quality and productivity due to involvement    of number of process parameter. Even in completely controlled process, defect in casting are observed and hence casting process is also known as process of uncertainty which challenges explanation about the cause of casting  defects. In order to identify the casting defect and problem  related to  casting, the study is  aimed in the research  work. This will be beneficial in enhancing the yield of casting. Beside this, standardization (optimization) of process parameter for entire cycle of manufacturing of the critical part is intended in the proposed work. This study aims to finding different  defects in casting, analysis of defect  and providing their remedies with their causes.  In this  paper   an attempt has been made to list different   types of casting defects and their root causes of occurrence. This paper    also aims to provide correct guideline to quality control department to find casting defects and will help them to  analyze defects which are not  desired.
