The wiredrawing mold is the steel wire produces the most important tool. In drawing process. The steel wire is achieves the basic size precision and the surface quality through the nib distortion. Mold material quality, nib geometrical shape, wiredrawing mold's structure and working immediate influence to steel wire quality and production efficiency. The modern wiredrawing toward the high speed, continuous and the automated direction develops. The wiredrawing mold manufacture, the use and the service level's enhancement realizes three important guarantees.

 The wiredrawing mold taxonomic approach has three kinds: According to the material quality classification, according to the textural classification, and according to draws the property sort.
 
1. the wiredrawing mold may divide into according to the material quality type:

  1st, steel die - - staking metal (for example money) when the steel die is sufficient, on the steel die may have many different aperture holes.

  2nd, the hard alloy mold - - drawn wire (steel wire) uses the carbide die generally (Tungsten carbide nib), this kind of mold's modular design is a cylinder (or slightly has taper) the hard alloy mold core mounts closely in circular steel bushing (case), in the mold core in the hole has the trumpet-shaped object (Bell radius), the approach cone (Entrance angel), the distortion (work) the awl (approach angle), to decide the diameter to bring (bearing) and the argument (back relief).

  3rd, the steel wire mold - - pulls colored Jin Shuxian, like copper, aluminum, also uses with the steel wire mold similar wiredrawing mold, in hole shape some differences.

  4th, the crystal combination mold - - pulls the fine lace as available as the crystal combination mold (man-made diamond), but also has with the natural diamond wiredrawing mold.

   (1) presses the material quality name naming wiredrawing mold is the domestic general method, the classification is as follows:

  Steel iron mold----Carbon steel die, alloy steel die, fresh iron mold
  Diamond mold----Rough diamond, artificial diamond (rough diamond fine powder crystal combination mold, artificial diamond fine powder crystal combination mold)
  Hard alloy mold----The tungsten cobalt hard alloy mold (including trace element, including trace element), the steel does not tie the hard alloy mold
  Cermet mold----The corundum is the ceramic mold, the silicon carbide is the ceramic mold
 
2. according to textural classification
  Entire phantom----Circular mold, different mold
  Build up pattern----Puts together the pattern making, the fluid Run slip form
 
3. presses draws the property sort
  Sliding contact mold
  Rolling contact mold----Roller draw die, revolving mold


Wiredrawing mold's use:

  The wiredrawing mold versatility, like the electronic device, the radar, the television, the measuring appliance and astronautics and so on use the high accuracy silk material as well as the commonly used tungsten wire, the molybdenum silk, the stainless steel wire, the electric wire electric cable silk and each kind gather the gold thread are come out with the diamond wiredrawing mold drawing, because the diamond wiredrawing mold uses the natural Jin'gang stonemason's workshop raw material, thus has the greatly strengthened resistance to wear, the service life is extremely high.
