ABSTRACT
In today’s world a casting production without any defect is almost impossible. After the application of various optimization techniques and process we still are not able to get the defect free castings. So it is critically important to analyze the root cause of casting defect with in the process itself, so that any changes which can hamper the defect intensity can be invoked at the time of manufacturing or foundry shop production. The gravity die casting process is governed by its process parameters so it is required to study its process parameters and its effects. In this paper an effort has been incorporated to study the change in process parameters and their consequent effects on casting defects.

INTRODUCTION
In practical foundry shop it is quite tough to judge the exact cause for a particular defect because they are quite intuitive in nature. So first of all it is required to identify process parameters which can affect the process considerably and can change the output with reasonable weightage. So it is required to identify the factors which can affect the process and these factors are identified with the help of study of various literatures and interaction with various foundry experts in different industries. According to experience and expertise of foundry experts and after studying various literatures there are lots more factors which are identified to be affecting the gravity die casting process considerably.
