What is Forging?

Forging is a manufacturing process where metal is pressed, hammered, or extruded under high pressure into a high-strength forging. The process is usually (but not always) performed in a hot state, where the metal is preheated to the desired temperature before processing. It is important to note that the forging process is completely different from the casting process because the metal used to make the forging is not melted and poured as in the casting process.

Why forging?

1. Forgings can withstand extreme pressures and maintain structural integrity under stress. Once produced, forgings are widely used in the military and other industries, such as heavy trucks, medical supplies, automotive parts, aerospace, etc.

2. The forging process produces metal parts that are stronger than any other metalworking process. The forging process uses the natural grain flow of the metal to conform to the unique geometry of each part. This grain flow profile is lost when the grain is cut by machining, and is also lost when the part is cast. Forgings provide a single-piece product, rather than welded parts, because weld quality is difficult to replicate without additional inspection.

3. Forgings can take almost any shape, reducing the need to join multiple parts. Because forgings do not require welding or other fastening methods, fewer joints can increase the overall strength of the part.
