Copper Wire Manufacturing Process - GANPATI …

Annealing of Drawn Wires: After drawing the wires, the next step is to convert these into annealed soft wires by performing annealing process in an electrical furnace. Tinning Process: For tinning or coating process, we pass the wires from Hot Dipping process and then Electroplating process. While at the first stage, wire get coated with tin and at the second stage these coated wires are taken for getting these immersed into electrolytic solution to set the coating on the wire.

Wire drawing - Wikipedia

The wire drawing process is quite simple in concept. The wire is prepared by shrinking the beginning of it, by hammering, filing, rolling or swaging, so that it will fit through the die; the wire is then pulled through the die. As the wire is pulled through the die, its volume remains the same, so as the diameter decreases, the length increases. Usually the wire will require more than one draw, through successively smaller dies, to reach the desired size. The American wire gaugescale is based on this. This can be done on a small sc…

Wire Drawing - an overview | ScienceDirect Topics

Wire drawing. The conventional process to produce metal fibres is wire drawing, a mechanical production process. This process is characterized by its various drawing steps, called coarse, medium, fine and carding trains. The drawing die, used to draw the fibre, consists of a steel mount with a core out of ceramics, carbide or diamond. The initial diameter of the metal wire varies, depending on the material. For copper, …
