Cold Working Sheet Metal

In cold forming metal is formed at high speed and high pressure using tool steel or carbide dies.

Cold working sheet metal. 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. Metal is said to be cold worked if it is mechanically processed below the recrystallization temperature of the metal. The cold working of the metal increases the hardness yield strength and tensile strength. Cold work is defined as the plastic deformation of a metal below its re crystallization 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. Sheet metal cold working can be used to produce controlled surface finish. In this method the shape changes but the volume of the metal remains constant. 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. Be it manual or powered equipment we have the solutions you need. 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. The steel bars we machine are typically cold drawn cold worked.

The force exerted by rollers on the sheet reduces its thickness and increase the strength of the sheet. Cold rolling is often used commercially in order to produce sheet metal plates and bars. Ftis split sleeve cold expansion system is a cost effective solution to problems associated with fatigue cracks in holes in metal structures. Most of cold working processes are performed at room temperature.

Cold working or cold forming is any metalworking process in which metal is shaped below its recrystallization temperature usually at the ambient temperature. The haynes and hastelloy alloys can be readily formed into various configurations by cold working.
