What is a factory that performs casting operations called?

A factory that performs casting operations is referred to as a foundry. This facility specializes in producing metal castings through the process of pouring molten metal into molds, allowing it to cool and solidify into the desired shape. Foundries are essential in manufacturing a wide variety of products, including industrial machinery, engine blocks, and artistic sculptures, among others.

The term "foundry" specifically highlights the operations associated with casting, which can involve various metals and alloys. In contrast, a workshop generally represents a space for working on smaller projects and repairs, while a forge is primarily associated with shaping metal through heating and hammering rather than casting. A mill is commonly associated with machining processes, grinding, or milling materials, rather than the casting processes that take place in a foundry. Thus, the distinction lies in the specific processes each facility emphasizes, making foundry the most accurate term for a factory dedicated to casting operations.
