Wire drawing dies are widely used, such as high-precision wire materials 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 drawn by diamond wire drawing die. The diamond wire drawing die has a strong wear resistance and a very high service life due to the use of natural diamond as a raw material.

Drawing die is a very important consumable mold for drawing wire rods of various metal wire manufacturers (such as wire and cable factories, steel wire factories, welding wire and wire factories, etc.). The wire drawing die has a wide range of applications, and is mainly used for drawing straight, difficult-to-machine objects such as bars, wires, wires, pipes, etc., and is suitable for drawing and processing of metal and alloy materials such as steel, copper, tungsten, molybdenum and the like. Since the cost of the wire drawing die accounts for more than 1/2 of the wire drawing cost, how to reduce the cost of the wire drawing die and increase its service life is an urgent problem to be solved by the metal wire production unit.
