Forging hammer is the most primitive method, ring forging processing equipment has forging hammer and hydraulic machine.

Auto parts forging manufacturer to use external force to change the shape of the metal, also is the use of forging hammer effect on metal huge external force, make the metal change in shape, this method is to make all the metal stress of ring forgings are relatively uniform, so in the use of more extensive, but the need when using forging hammer forging high temperature environment, processing because want metal deformation occurs, just need to change the hardness of the metal, and some of the high melting point metal in the use of forging hammer forging when you will have trouble.

Is the use of hydraulic press,hydraulic press is through the static pressure produced by the liquid to change the shape of the forging so that there is no need for higher temperature, so a lot of large ring forging is the use of hydraulic forgings.
