The first step in the production process of silica sol precision casting is to make investment molds. In the process of use, it is mainly used to form a model of the cavity in the refractory shell, so that castings with high dimensional accuracy and surface finish can be obtained.

Despite these challenges, sand casting remains an enduring and vital part of the manufacturing landscape. Its flexibility, cost-effectiveness, and capability to produce complex shapes make it a preferred choice for many applications. From historical artifacts to the latest automotive components, sand casting continues to bridge the gap between traditional craftsmanship and modern technology, preserving a rich legacy while adapting to the demands of contemporary manufacturing.
