Forging and stamping

North American Industry Classification System code (NAICS): 3321

This industry group comprises establishments primarily engaged in shaping hot metal by forging to produce a part near its final size and shape; or pressing and cutting sheet metal stock to form stampings. These establishments generally operate on a job or order basis, manufacturing metal stampings or forgings for sale to others or for inter-plant transfer. These establishments may surface-finish the forgings and stampings produced, by such activities as deburring and grinding, but they do not further process them.
