A foundry is a factory that produces metal castings by pouring liquid metal into a mold. The mold can be made of metal, sand, or a ceramic substance.
The casting process involves the following steps: Patternmaking Creating a mold Melting metal Pouring the metal into a mold Waiting for it to solidify Removing it from the mold Cleaning and finishing the object
Foundries play a significant role in a country's industrial development. They produce metal components for industrial needs such as pumps, valves, compressors, and engines. They also produce machine parts such as gears, shafts, and couplings used in mechanical systems.
Some types of casting processes include: Sand casting: Also known as sand molded casting, this process uses sand as the mold material. It is relatively cheap and refractory enough for steel foundries. Kneaded sand is highly liquid, so no firing process is required. Investment casting: This process involves surrounding a pattern with a refractory material. Many materials are suitable for investment casting, including stainless steel alloys, brass, aluminum, carbon steel, and glass.
