Castings are critical components in various industries, including automotive, aerospace, and machinery. They are created by pouring molten metal into a mold, allowing it to solidify into a desired shape. This process enables the production of complex and intricate parts that are often too difficult or costly to manufacture through other methods. Castings can be made from a range of metals, including iron, steel, aluminum, and bronze. They are valued for their durability, strength, and ability to withstand extreme conditions, making them ideal for use in heavy machinery, engine blocks, and structural components.
