2. Hollow Cores Designed to produce hollow sections, these cores allow for lightweight construction of parts, which is critical in industries such as automotive and aerospace.

Despite its many advantages, sand casting does come with challenges. The process can produce defects such as porosity, which can compromise the integrity of the engine block. Additionally, the surface finish may require further machining, which can add to production costs. Therefore, manufacturers must implement rigorous quality control measures to ensure that the final product meets stringent standards.

1. Investment Casting Also known as lost-wax casting, this method involves creating a wax model of the desired part, which is then encased in a ceramic material. Once the ceramic material hardens, the wax is melted away, leaving a precise mold. Molten metal is then poured into the mold, resulting in highly detailed and accurate components.
