How the Cold Drawing Process Works

In the cold drawing process, standard shape bars (rounds, squares, hexagonals or flats) are pulled through carbide dies which have been contoured to the exact shape of the part you need. The drawing process changes the shape or reduces the size of the metal. Several passes may be required through smaller and smaller dies depending on the final shape, or the complexity of the finished product. Sometimes annealing may be required between the drawing operations to restore the ductility of the metal.
