Foundry processes are methods used to create metal parts by pouring molten metal into molds. This process begins with melting metal, often using a furnace, and then shaping it into a desired form. The molds can be made from various materials, such as sand or metal, and are designed to withstand high temperatures. Once the metal cools and solidifies, the mold is removed, revealing the finished part. These processes are essential in industries like automotive and aerospace, where precision and durability are crucial. Techniques such as sand casting, investment casting, and die casting are commonly used to produce everything from small components to large machinery parts.
