Basic types of drawing die

1. A steel mold is sufficient when drawing soft metals (such as gold and silver), and the steel mold can have multiple holes with different diameters.

2. Tungsten carbide die-drawn 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 tightly inlaid In a round steel case (case), the inner hole of the mold core has a bell (Bellradius), an entrance cone (Entranceangel), a deformation (working) cone (approachangle), a sizing belt (bearing) and an exit angle (backrelief) .

3. Steel wire dies-for drawing non-ferrous metal wires, such as copper and aluminum, wire drawing dies similar to steel wire dies are often used, and the inner hole shapes are somewhat different.

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.
