Description
Along with the increasing speed of wiredrawing machine and growing wire take-up weight as well as the decreasing manpower to be manned to the machine, the wire drawing efficiency has undergone remarkable improvement. For the higher drawing efficiency, the most critical requirement is that the copper wire will not be broken during drawing. Recently the demand on superfine to ultra fine wires is growing, and in this wire size range, the wire break frequency governs the industrial applicability of the material and wiredrawing technology.
