Sand casting involves creating a mold from sand, which is then filled with molten metal to form a desired shape. The process typically includes several steps pattern creation, mold preparation, pouring, and cooling. Traditionally, patterns are often made from wood or metal, which can be labor-intensive and time-consuming to produce. The patterns must be designed to allow for the shrinkage of the metal during cooling and to facilitate the removal of the cast from the mold. This highlights one of the primary challenges in sand casting designing for manufacturability while accommodating the limitations of conventional materials and techniques.

1. Creating Internal Features The primary purpose of a core is to form internal features that cannot be crafted from the outer mold. For example, cores are essential in producing cylindrical holes, chambers, or other shapes within the cast part. These features are often critical for the part's functionality.

5. Pouring the Metal With the mold ready, molten metal is poured into the cavity. Due to the smooth surface of the plaster, the final cast is obtained with much finer details compared to traditional sand casting.

4. Finishing After machining, cores undergo finishing processes, such as polishing and surface treatment, to enhance performance and durability.

- Local Suppliers Many foundry sand suppliers operate regionally, which can save on shipping costs and provide easier access for bulk purchases. It's beneficial to evaluate multiple suppliers to get competitive prices.
