Wire drawing die usually refers to various dies for drawing metal wires, as well as wire drawing dies for drawing optical fibers. All drawing dies have a hole in the center of a certain shape, round, square, octagonal or other special shapes. The metal becomes smaller in size and even changes shape as it is pulled through the die hole. When pulling soft metals (such as gold and silver), a steel mold is sufficient, and the steel mold can have multiple holes of different diameters.

Wire drawing die is widely used, such as high-precision wire used in electronic devices, radar, television, instrumentation and aerospace, as well as commonly used tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire and various alloy wires are all diamond wire drawing dies The drawn diamond wire drawing die has strong wear resistance and extremely high service life due to the use of natural diamond as raw material.
With the deepening of reform and opening up, wire drawing die and corresponding die hole detection instruments made by industrialized countries have been introduced in China one after another. Through the analysis of foreign wire drawing die hole pattern, we can understand the design idea of modern wire drawing die hole pattern, which provides reference for improving the design level of wire drawing die in China.
