Cold Working Sheet Metal

Meaning of cold working.

Cold working sheet metal.

When a metal is cold rolled it is plastically deformed as it is forced between the two rolls. The haynes and hastelloy alloys can be readily formed into various configurations by cold working. The cold working of the metal increases the hardness yield strength and tensile strength. In the precision machining industry cold working processes can include thread rolling thread forming swaging crimping staking planishing and metal spinning.

The force exerted by rollers on the sheet reduces its thickness and increase the strength of the sheet. Cold work is defined as the plastic deformation of a metal below its re crystallization temperature. Such processes are contrasted with hot working techniques like hot rolling forging welding etc. Cold rolling is often used commercially in order to produce sheet metal plates and bars.

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. The steel bars we machine are typically cold drawn cold worked. 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.

Be it manual or powered equipment we have the solutions you need. 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. 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. 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.
