Investigating the causes and remedies for porosity defects in the casting process: A review

Abstract

The casting process is a crucial manufacturing method utilized in numerous sectors to create intricate components
and forms. However, there are a number of underlying causes of casting flaws that can result in subpar quality,
higher costs, and decreased productivity. This review seeks to give a general overview of casting process flaws,
their causes, and possible fixes. The evaluation will go over the various possible flaws, including porosity,
shrinkage, and surface abnormalities, as well as their underlying causes, which include design, material, and
process characteristics. Furthermore, the review will focus on various remedial measures that can be taken to
overcome these defects and improve casting quality, such as changes in design, material selection, and process
optimization. This review will be useful for researchers and practitioners in the casting industry who are interested in
improving their understanding of casting defects and developing effective remedial measures to enhance product
quality and efficiency
