The uniform wire drawing and straightening equipment for the core wire of the enameled wire usually consists of a wire drawing machine and a straightening machine. The wire drawing machine is used to draw the core wire of the enameled wire through a series of wire drawing rollers to make the diameter of the wire uniform and fine, and improve the strength and conductivity of the wire.
