High precision casting encompasses several methods, the most common of which are lost-wax casting and investment casting. In lost-wax casting, a pattern made from wax is coated with a ceramic material to create a mold. Once the mold setting is complete, the wax is melted away, leaving an empty cavity. Molten metal is then poured into this cavity and allowed to solidify, resulting in a precise metal replica of the original wax component.

Cast iron is an alloy of iron that is rich in carbon and silicon. Its high carbon content gives it excellent casting properties, allowing it to be poured into intricate molds, which is why it is widely used in the manufacturing of heavy-duty cookware, engine blocks, and decorative items. The various types of cast iron—such as gray iron, ductile iron, and white iron—have distinct properties, influencing how they are processed and finished.
