1. The definition of wire drawing dies
usually refers to various dies for drawing metal wires, as well as drawing dies for drawing optical fibers. All drawing dies have a hole in the center of a certain shape, round, square, octagonal or other special shapes. When the metal is pulled through the die hole, the size becomes smaller and even the shape changes.
2. Types of wire drawing dies
1. Steel dies- steel dies are sufficient for drawing soft metals (such as gold and silver). The steel dies can have multiple holes with different diameters.
2. Tungsten carbide die-drawn steel wire (steel wire) generally uses a tungsten carbide die (Tungsten carbide nib), the typical structure of this type of die is a cylindrical (or slightly tapered) cemented carbide core tightly The ground is embedded in a circular steel case. The inner hole of the mold core has a bell radius, an entrance cone, an approach angle, a bearing, and Exit angle (back relief).
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, 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.
