Hot forging is a manufacturing process in which metal is heated to a specific temperature and then shaped using pressure from a press or hammer.
There are several different types of hot forging, including:
Upset forging is a process in which a metal rod or bar is heated and then compressed between two dies to increase its diameter and decrease its length. This process is commonly used to produce fasteners, such as bolts and screws.
Open-die forging, also known as smith forging, is a process in which metal is heated and shaped using a hammer or press. The metal is not confined by a die, allowing for greater flexibility in the size and shape of the final product. This process is commonly used to produce large, heavy components, such as turbine shafts, crankshafts, and gears.
