What is Forging
Forging is a processing method that presses the metal by hammering or pressing to make it plastically deformed, so as to change the lattice arrangement of the metal, reduce the internal voids, eliminate defects, and improve the strength, toughness and other mechanical properties of the metal. According to the processing method, it can be divided into the following three types:
- Open Forging: Without using a die, the metal is repeatedly hammered to deform it, which is suitable for forging blanks of non-standard large parts.
- Die forging: The metal is pressed into the die by pressure, which has high production efficiency and is used to produce complex shape parts.
- Roll forging: Using the fan-shaped die on a pair of counter-rotating rolls, the metal blank is rolled in multiple passes, and gradually rolled into a forging of the desired shape. It is suitable for forging shafts or flat forgings.
Advantages of Forging
The main advantages of forging compared with other metal processing processes are reflected in the following aspects:
- Excellent mechanical properties
- Near-net shaped, high material utilization
- High consistency, suitable for mass production
Any processing method has its drawbacks, and forging is no exception. Its disadvantages are mainly reflected in the high cost of tooling (especially die forging) and the low precision, which often requires additional machining for high-precision applications.
