Analysis of casting defect and methodologies adopted for defect reduction/quality improvement- A Review

Mechanical Engineering

In today’s world of rapid globalization, foundry industries of India play a key role of production goods by using casting process. Today is the era of customer driven market, due to this industries are needed to produce defects free product and processes to satisfy customer requirements. Casting process is the most widely used process in industry specially in the filed of Automotive product manufacturing but defect free casting poses a critical threat in its development as compared to other manufacturing approaches.Casting involves various process like mould making, core making, melting , pouring, and solidification. Casting have one or more defects and these defects may be the the result of single cause or combination of causes.These defects increase the rate of scrap and increase overall production cost.Some defects can be tolerated while others can be repaired, otherwise they must be eliminated. The aim of this paper is to review the existing research progress in the field of foundry and methodologies adopted to produce defect free casting.
