For the production of wire several different types of machines are required. First of all there is a difference between the drawing of iron / steel wires and copper or aluminium wires due to the required forces. While copper / aluminium wire is reduced 10 times or more in one machine, drawing machines for ferrous wire have only very seldom more than 10 drawing steps. Also the drawing capstans are a lot bigger in ferrous machines as well as the motors driving the machine. Non-ferrous wire drawing machines are also often equipped with inline annealers to heat up the wire after the drawing process in order to make it soft again. There are a lot of other machines required for the wire drawing process, these include:
