What is forging

Forging is a manufacturing process that uses localized compressive forces to shape metal. Traditionally, a hammer was used against an anvil, but now more often a die is used. Jiahangaero refers to three forging processes: hot forging, warm forging and cold forging. Widely used in mechanisms and machinery, forging can produce parts that are stronger than equivalent cast or machined parts whenever high strength is required in the part.

The benefits of forging

• Forging provides uniformity of composition and structure. As the metal is formed during the forging process, its internal grain deformation follows the general shape of the part. Thus, the texture is continuous throughout the entire part, giving a piece with improved strength properties. This strengthens the resulting steel product, especially in terms of impact and shear strength.

• Rugged and reliable. Forged metal parts offer superior strength over other metalworking processes. The high strength is a result of the tight grain structure of the wrought metal. The strength and reliability of forged products exceeds that of cast, fabricated and welded products. Due to the grain structure of forgings, forgings can still maintain their properties in a wide temperature range.

• High cost performance. Jiahangaero says the forging process offers significant cost advantages, especially in precision metal fabrication in high-volume production runs. Materials used in forging are less expensive than other materials used in metalworking processes. Also, it requires fewer secondary operations in most cases. With high precision, it can obtain finishing materials with precise dimensions and good surface finish. That's why it requires a low machining and provides a way to be cost effective.
