Cold Working Sheet Metal

Cold working or cold forming is any metalworking process in which metal is shaped below its recrystallization temperature usually at the ambient temperature.

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. The cold working of the metal increases the hardness yield strength and tensile strength. Be it manual or powered equipment we have the solutions you need. 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. Most of cold working processes are performed at room temperature. The haynes and hastelloy alloys can be readily formed into various configurations by cold working. Meaning of cold working.

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. Such processes are contrasted with hot working techniques like hot rolling forging welding etc. In cold forming metal is formed at high speed and high pressure using tool steel or carbide dies. 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.

In the precision machining industry cold working processes can include thread rolling thread forming swaging crimping staking planishing and metal spinning. Cold work is defined as the plastic deformation of a metal below its re crystallization temperature. When a metal is cold rolled it is plastically deformed as it is forced between the two rolls. 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. The force exerted by rollers on the sheet reduces its thickness and increase the strength of the sheet.
