The rebar upsetting forging machine is a specialized piece of construction equipment that applies the cold heading principle to achieve plastic deformation of rebar ends. Unlike conventional processing methods, this machine compresses the rebar end to increase its diameter by 4mm, and then processes standard threads on the thickened end. The core advantage of this process is that the actual sectional area of the processed rebar end exceeds that of the original rebar, which drastically improves the tensile strength of the rebar joint. A standout result of this technology is that the threaded joints formed after upsetting forging consistently break in the parent rebar material rather than the joint itself—a critical performance feature for engineering projects with high connection strength requirements, ensuring the joint never becomes the weak link in the structural reinforcement system.
