Cold Working Sheet Metal

The process consists of a set of two or more rollers spaced closed together and the sheet or strip of metal is passed through them.

Cold working sheet metal.

Metal is said to be cold worked if it is mechanically processed below the recrystallization temperature of the metal. The force exerted by rollers on the sheet reduces its thickness and increase the strength of the sheet. Cold working or cold forming is any metalworking process in which metal is shaped below its recrystallization temperature usually at the ambient temperature. The cold working of the metal increases the hardness yield strength and tensile strength.

Most of cold working processes are performed at room temperature. Bending of sheet metal is another process for cold working which involves deforming metal over a work axis thereby creating a change in the geometry of the metal. Meaning of cold working. Be it manual or powered equipment we have the solutions you need.

Sheet metal cold working can be used to produce controlled surface finish. When a metal is cold rolled it is plastically deformed as it is forced between the two rolls. In cold forming metal is formed at high speed and high pressure using tool steel or carbide dies. Ftis split sleeve cold expansion system is a cost effective solution to problems associated with fatigue cracks in holes in metal structures.

Cold rolling is often used commercially in order to produce sheet metal plates and bars. Since they are generally stronger and work harden more rapidly than the austenitic stainless steels the application of greater force is normally required to achieve the same amount of cold deformation. Sheet metal machines quality fabrication equipment from a company you can trust from job shop to industrial grade fabrication shops around the world power up your sheet metal fabrication performance with coldworks equipment by fabrication solutions technologies fst. The steel bars we machine are typically cold drawn cold worked.

In the precision machining industry cold working processes can include thread rolling thread forming swaging crimping staking planishing and metal spinning. Such processes are contrasted with hot working techniques like hot rolling forging welding etc.
