Rebar Upsetting forging Machine using hydraulic cold heading of the principle of plastic deformation of steel ends, the diameter increases 4 ~ 6mm, and then processing thread. So that the actual cross-sectional area after processing thread larger than the original cross-sectional area of steel, greatly improving the tensile strength joints.
