A foundry is a facility where metal casting is performed. In this process, molten metal is poured into molds to create various shapes and products. Foundries can work with different types of metals, including iron, aluminum, and copper, depending on the desired outcome. Foundries play a crucial role in manufacturing industries, producing components for machinery, vehicles, and construction. The casting process allows for complex designs that would be difficult to achieve through other methods. Safety measures are essential in foundries due to the high temperatures and hazardous materials involved in metalworking.
