“…For example, sand inclusion is a type of defect that results from sand particles becoming trapped within the casting. Remedies for sand inclusion defects include using high-quality molding sand, controlling the sand moisture content, and maintaining proper molding and core-making practices (23).…”

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.

“…The wheel rim uses aluminum as the base material since it has many advantages such as lightweight, cost-effective and superior mechanical strength [3]. The wheel rim is commonly produced using sand casting and can also be produced through high/low-pressure casting [4]. Despite some technical advantages, the proposed method is relatively expensive, making it only suitable for a high-end component.…”

This research investigates the impact of varying the slope of the top mold in the gravity casting process of aluminum alloy (A356). The casting mold slopes were adjusted to 7°, 12°, and 17° angles, and the study integrates software analysis (Altair, 2021.2) with physical examinations to assess potential defects in the casted products. The findings from both approaches exhibit a consistent pattern, revealing notable defect porosities in molds with slopes of 7° and 12°. Radiography examinations provide insights into defect distribution within the hub wheel rim, particularly pronounced in molds with slopes of 7° and 12°. This observation suggests that disturbances in air and heat distribution impede the solidification process within the mold. Metallography profiles further highlight the presence of phases α (Al), β (Si), and the eutectic region in the casted product. Defect severity is prominently manifested in a fractured profile, particularly for products cast with a 7° slope. In contrast, a higher slope of 12° results in localized porosities and effectively mitigates defect distribution. The most favorable outcome, devoid of substantial defects, is achieved with a 17° mold slope, successfully passing stringent quality checks.
