In metal pressure processing, the metal is forced to pass through the mold under the action of external force, the cross-sectional area of the metal is compressed, and the thing that obtains the required cross-sectional area shape and size is called a wire drawing die.

Wire drawing dies are widely used, such as high-precision wires used in electronic devices, radar, television, appearance and aerospace, as well as commonly used tungsten wires, molybdenum wires, stainless steel wires, wire and cable wires and various alloy wires are all drawn with diamond wire drawing dies The produced diamond wire drawing die has extremely strong wear resistance and extremely long service life because it uses natural diamond as the material. The production technology of wire drawing die inserts includes several technical steps such as pressing die, drawing die and turning.

The wire drawing die is the metal wire passing through a mold to make it from thick to thin, gradually reaching the scale that everyone needs. This special mold is the drawing die. The core of the drawing die is usually made of natural diamonds, artificial diamonds (artificial diamonds) Diamonds include GE, PCD, composition materials, etc.). Copper wire drawing dies are classified as soft wire drawing dies. There are also hard wire drawing dies, such as tungsten wire. The viewpoint of the compression zone of copper wire drawing dies is usually 16-18 degrees. The fixed diameter length is 30-40%, and the viewpoint of the tungsten wire drawing die shrinking zone is relatively small, usually 12-14 degrees, and the fixed line length is 60-70%.

The wire drawing dies include diamond wire drawing dies, cemented carbide wire drawing dies, plastic wire drawing dies, etc. There are many more uses.
