Advantages and disadvantages of different forging processes for metal materials

Forging is defined as the forming or deformation of a metal in its solid state. Many forging is completed by upsetting process. In the upsetting process, the hammer or striker moves horizontally to press on the rod or the end of the rod to widen and change the shape of the end. Parts usually pass through successive stations before reaching the final shape. High strength bolts are "cold headed" in this way. Engine valves are also formed by upsetting.

How is the metal hose pre compressed before installation?

The metal hose mainly has two stages: the bulging stage, in which both ends of the tube and the forming die are fixed, and the wall tube expands radially under the restriction of the die and the effect of the liquid pressure in the tube. The degree of bulging is relatively small, and its purpose is to make the forming die axially positioned on the pipe. In the two stages of forming, the tube is further bulged under the combined action of internal pressure and axial pressure.
