The drawing die is very widely used, and can be used for the production of a variety of wires, cutting cutting wire, steel cord, wire and cable, gas shielded welding wire, flux cored wire, electronic wire, silver plating, tin plating, gold wire, automotive wire, tube Road, construction line, rigging line, optical fiber.

In various industries, such as electronic devices, radar, television, instrumentation and aerospace, high-grade wire materials and commonly used tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire and various alloy wires are drawn with diamond wire drawing die The diamond wire drawing die produced by using natural diamond as a raw material has extremely strong wear resistance and can be extremely high.

In metal pressure processing. Under the action of external force, the metal is forced to pass through the mold, the metal cross-sectional area is compressed, and the tool to obtain the required cross-sectional shape and size is called a drawing die. The drawing die is a metal wire passing through a die, so as to gradually reach the size that people need from thick to fine. This special die is a drawing die.

The core of the drawing die is usually made of natural diamond, synthetic diamond polycrystalline (PCD, CD composite, etc.). Copper wire drawing die belongs to flexible wire drawing die. There are also hard wire drawing dies, such as tungsten wire drawing. The angle of the compression zone of the copper wire drawing die is generally 16-18 degrees, and the sizing length is 30-40%, while the angle of the compression zone of the tungsten wire drawing die is relatively small, generally 12-14 degrees, and the fixed line length is 60- 70%.
