• Forming Service
  • Metal forming is a general term for a large group, that includes a wide variety of manufacturing processes like bending and rolling. Metal forming processes are characteristic in that the metal being processed is plastically deformed to shape it into a desired geometry. In order to plastically deform a metal, a force must be applied that will exceed the yield strength of the material. When low amounts of stress are applied to a metal it will change its geometry slightly, in correspondence to the force that is exerted.
