Cold drawing of metals is the process used to reduce the diameter of a metal wire by making it go through a smaller hole. This operation takes advantage of the ductility of certain metals, namely their ability to be deformed in cold conditions thereby giving them another size and another form. There are numerous advantages in cold drawing metals. At the beginning of the process an end of a round or wire is initially pointed so it can be inserted into the die and then gripped by the jaws of the drawing machine. The metal can be drawn in tandem by making the wire pass through a series of dies. Cold drawing work-hardens the material. For cold serial drawing of metals, annealing is required between one pass and the next. B&W counts cold drawing lines among its products and in fact actually makes cold drawing lines for metals, but not only; B&W makes industrial machinery designed to work steel and metal used in building and in the production of electrowelded steel structures.
