Wire drawing die application range

Wire drawing dies are widely used and can be used for the production of a variety of wires, polysilicon cutting wires, steel cords, wires and cables, gas shielded welding wires, flux-cored welding wires, electronic wires, silver-plated, tin-plated, gold wires, automotive wires, pipelines , Construction wire, rigging wire, optical fiber.

In various industries, high-precision wires used in electronic devices, radar, television, instrumentation and aerospace, as well as commonly used tungsten wires, molybdenum wires, stainless steel wires, wire and cable wires, and various alloy wires are all used with diamond wire drawing dies The drawn, diamond wire drawing die adopts natural diamond as raw material, so it has strong wear resistance and extremely long service life.

In metal pressure processing. Under the action of external force, the metal is forced through the die, the cross-sectional area of the metal is compressed, and the tool that obtains the required cross-sectional area shape and size is called a drawing die. The wire drawing die is a kind of die for the metal wire to gradually reach the size that people need from thick to thin. This special die is the wire drawing die.

The core of the drawing die is generally made of natural diamonds, synthetic diamond polycrystalline (PCD, CD composite materials, etc.). Copper wire drawing die is a flexible wire drawing die. There are also hard wire drawing dies, such as drawing tungsten wires. 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. %.
