The process begins with mixing sand with resin in specific proportions to create a sand mold. Once the mixture is prepared, it is shaped into patterns that form the cavities for the cast metal. The molds are then heated to cure the resin, which solidifies the sand particles and forms a robust mold. After the mold is prepared, molten metal is poured into it, and once it solidifies, the mold is broken away to reveal the final product.
