1. Steel mold is enough for soft metal (such as gold and silver), and there can be multiple holes with different aperture on steel mold.

2. Hard alloy mold-drawing steel wire (steel wire) is generally used carbide die mould(Tungsten carbide nib), the typical structure of this mold is a cylindrical (or slightly taper) hard alloy mold core tightly embedded in a round steel sleeve (case), mold core inner hole has Trumpet (Bell radius), inlet cone (Entrance angel), deformation (work) cone (approach angle), sizing band (bearing) and exit angle (back relief).

3. Steel wire die-drawing colored metal wire, such as copper and aluminum, is also widely used in wire drawing die similar to steel wire die, with some differences in inner hole shape.

4. Polycrystalline mold-pull hairline rule can be used to polycrystalline mold ( artificial Diamond), there are also wire drawing dies that use natural diamonds.
