Forging is mainly divided into open-die forging and closed-die forging. Open die forging does not require the use of molds, has low precision, requires subsequent finishing, and is suitable for small batch production of large parts. Closed die forging requires the use of molds, which can produce parts with high precision and complex shapes.
Compared with CNC machining, the disadvantage of forging is the lack of flexibility. But the advantages of forging are equally obvious, it changes the internal lattice structure of the metal by high temperature and pressure, can produce parts with higher strength than other processing methods. Forging is a better choice when mass-producing key components that require high strength (such as connecting rods, gears, shafts, etc.).
In the actual production process, a variety of processes are often required to cooperate with the production of a product. CNC machining is mostly used in the post-processing process of forging and casting parts.
