Plastic working

Plastic working is a process of forming a material, such as metal, into a desired shape by applying large force. The property where deformation caused by the application of force does not return to the previous state with a permanent deformation even after the force has been removed is called plasticity.
There are various methods of plastic working, including forging, rolling, and shearing. With low material loss and high working speed, this type of processing is used for many industrial products.

At FINECS, terminals and pins are produced by successive operations of cutting and hitting of metal wire to cause plastic deformation. Having a continuous grain flow, products made by plastic working are also resistant to stress.
