Forming processes make use of stresses like compression, tension, shear, or some combination to cause the plastic deformation of a material into a desired shape. This manufacturing process is typically for plastics and metals.
No material is added or subtracted in this process. The workpiece is only deformed or displaced. Linear materials such as steel tube, pipe, or rod, and sheet materials such as steel plate or thermoplastic can be bent, curved, sliced, embossed, or deformed into shape through the application of external pressure and/or heat. Such transformation requires tools that can bend, fold, or deform using molds, punches, stamping dies, or bending tools. Material consumption is greatest in this process when molds are used.
