Foundries & Forges
Foundries and forges are facilities which manufacture whole metal parts. Often used to manufacture the same types of parts, such as automotive crankshafts, forges and foundries use very different processes, each with its own benefits and drawbacks. A foundry is a facility which manufactures metal castings, a process which uses a closed mold (or die) to shape molten metal into specific, mid to high tolerance parts. Forges, or smithies, use hot and cold hammering and stamping processes to shape metal pieces that are still in solid form.
Because the products fabricated by casting and forging are often similar, the term “foundry” is often used to refer to a facility that manufactures forgings, which is a misnomer; foundries manufacture castings, and forges (also called “smithies") manufacture forgings.
