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.

In this method the shape changes but the volume of the metal remains constant. When a metal is cold rolled it is plastically deformed as it is forced between the two rolls. The force exerted by rollers on the sheet reduces its thickness and increase the strength of the sheet. 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.

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. 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.

Most of cold working processes are performed at room temperature. In cold forming metal is formed at high speed and high pressure using tool steel or carbide dies. The haynes and hastelloy alloys can be readily formed into various configurations by cold working. Be it manual or powered equipment we have the solutions you need.

Ftis split sleeve cold expansion system is a cost effective solution to problems associated with fatigue cracks in holes in metal structures. 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. 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.

Metal is said to be cold worked if it is mechanically processed below the recrystallization temperature of the metal. Meaning of cold working.
