A foundry is a facility where metal casting is performed. In this process, molten metal is poured into molds to create various shapes and objects. Foundries can work with different types of metals, including iron, aluminum, and copper, and they are essential in manufacturing industries for producing parts used in machinery, vehicles, and construction. Foundries utilize various techniques, such as sand casting and investment casting, to achieve the desired results. The process involves several steps, including melting the metal, preparing the mold, pouring the metal, and finishing the cast product. Foundries play a crucial role in the production of both small and large-scale metal components.
