Forging Equipment, Cold Forging Press, Upsetter
In the concrete pole manufacture, an upset forging machine increases the diameter of the metal workpiece by compressing its length. It's applied to increase the prestress and bearing capacity of the steel bar.
In accordance to different processing modes, the forging machine has two types, cold forging and hot forging. Advantages of cold forging are cheap and easy operation. As for hot forging, it finishes the forging process quickly, with low failure rate, due to the installation of a pneumatic pressure system.
