Detailed introduction of the four types of wire drawing die
1. Steel molds-steel molds are sufficient when drawing soft metals (such as gold and silver). The steel molds can have multiple holes with different diameters.
2. Tungsten carbide die-drawing steel wire (steel wire) generally adopts tungsten carbide die (Tungstencarbidenib). The typical structure of this type of die is a cylindrical (or slightly tapered) cemented carbide die core that is tightly inlaid In a round steel case, there are Bellradius, Entranceangel, Approachangle, Bearing and Backrelief in the inner hole of the mold core .
3. Steel wire dies-for drawing non-ferrous metal wires, such as copper and aluminum, wire drawing die similar to steel wire dies are often used, with some differences in the shape of the inner holes.
4.Polycrystalline molds-Polycrystalline molds (man-made diamonds) can be used to draw thin wires, as well as wire drawing molds that use natural diamonds.
