Wire Drawing dies
Wire drawing molds are widely used, such as electronic devices, radar, television, instruments and aerospace and other high-precision wire, as well as commonly used tungsten wire, molybdenum wire, stainless steel wire. Wire cable wire and all kinds of alloy wire are drawn by diamond drawing die. The diamond drawing die has extremely strong wear resistance and long service life because of the use of natural diamond as raw material.
