Several kinds of wire drawing die material

       

Wire drawing die 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.

Material of 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-drawn steel wire (steel wire) generally uses a tungsten carbide die (Tungsten carbide nib). The typical structure of this die is a cylindrical (or slightly tapered) cemented carbide die core. The ground is inlaid 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, and the shape of the inner hole is somewhat different.

4. Polycrystalline molds-polycrystalline molds (man-made diamonds) can be used to draw thin wires, and wire drawing molds that use natural diamonds
