What is Casting?

Casting is a manufacturing process where molten, liquid metal is poured into a mold and is left to cool to conform to the mold’s shape when solidified. Casting has been used for thousands of years, where ancient people would cast brass, iron, copper, and other metals into jewelry, weaponry, and more. Since then, casting has become the foremost tool used by manufacturers to create highly complex, homogenous, and replicable metal products. From raw materials to intricate assemblies, casting is an invaluable additive process that reduces the need for difficult machining and other subtractive methods.

To learn about this metal fabrication technique and its modern implementations, read our article about the types of casting processes.

What is a casting company, and what do they do?

A casting company performs casting procedures on steel and other metals (such as foundries) and/or sells and distributes cast parts for buyers. Casting companies have specialized equipment to perform specific techniques such as investment casting, die casting, sand casting, etc., often with built-in automation and control. Some casting companies will pair with buyers to manufacture parts for them under a contract basis (i.e. produce 10,000 parts, perform casting for a year, etc.). These contract services allow parts procurement without the weighty overhead costs of in-house casting equipment, space, and workers.

There are hundreds of casting companies in the market, but this article will detail today’s top U.S. and top global metal casting companies.
