1, pull soft metal (such as gold and silver) when the steel mold is sufficient, the steel mold can have a number of different pore holes.
2, carbide die-drawn steel wire (steel wire) in general, the use of carbide molds, the typical structure of this mold is a cylindrical (or slightly tapered) carbide core is tightly inlaid in a round steel sleeve, the core inside hole has trumpet, inlet cone, deformation (work) cone, sizing belt and exit angle.
3, steel wire mold-pull non-ferrous metals, such as copper, aluminum, but also more use and steel wire mold similar to the drawing die, the shape of some differences in the hole. 4, polycrystalline mold-pull thin lines can be used to polycrystalline mold (synthetic diamond), but also useful to the natural diamond wire drawing die.
