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.

　　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:

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.
