Bolt head forging
WebOct 1, 2014 · The cold forging manufacturing process increases the strength of a metal through strain hardening at a room temperature. On the contrary the hot forging manufacturing process keeps materials from strain hardening at high temperature, which results in optimum yield strength, low hardness and high ductility. Finally, a manufacturer … WebThe steel wire is moulded into the correct shape at room temperature using cold forging / forming / heading machines. The head of the bolt or screw is progressively formed by forcing the steel into various dies at high pressure. The screw or bolt threads are formed by rolling or cutting. The fastener is exposed to extreme heat to harden the steel.
