Provided is a forming system including: a forming device including a fluid supply unit that supplies a fluid to a heated metal pipe material, and a forming die that forms a formed product by bringing an expanded metal pipe material into contact with a forming surface; a machining unit that machines the formed product removed from the forming die; and a scale removing unit that removes scales from the formed product machined by the machining unit.

A method of providing an electrical grounding point on an aluminum structural member of a motor vehicle. The member is hydro-formed to produce a closed cross-section, after which a hole surrounded by a flange is formed in a wall of the member. The flange is generally the shape of a truncated cone and extends toward an interior of the member. A self-tapping fastener having a grounding lead attached thereto is driven into the hole to cut threads into the flange and secure the grounding lead to the member. The self-tapping fastener allows the grounding connection to be achieved without any access to the hollow interior of the member as would otherwise be required.

By the control of a controller, a gas is supplied into a metal pipe material from a gas supply part so as to expand a part of the metal pipe material in sub-cavity parts, and then a driving mechanism is driven such that expanded parts of the metal pipe material are pressed by an upper die and a lower die to form flange parts. In addition, by the control of the controller, a gas is supplied into the metal pipe material after the formation of the flange parts from the gas supply part so as to form a pipe part in a main cavity part. In this manner, the controller controls the gas supply part and the driving mechanism, and thus flange parts and a pipe part having a desired shape can be easily formed.
