What are the types of wire drawing machine molds?
The drawing machine mold can be roughly divided into the following four types:
1. Steel molds-steel molds are sufficient when pulling soft metals (such as gold and silver). There can be multiple holes with different diameters on the steel molds.
2. Carbide models-drawn steel wire (steel wire) generally adopts carbide die (Tungsten carbide nib), the typical structure of this die is a cylindrical (or slightly tapered) carbide die core It is embedded in a round steel case, and there are bell radius, entrance angel, approach angle, bearing and Back relief.

3. Steel wire molds-drawing non-ferrous metal wire, such as copper and aluminum, also uses wire drawing mold similar to steel wire mold, the shape of inner hole is somewhat different.
4. Polycrystalline molds-polycrystalline molds (artificial diamonds) can be used for drawing thin wires, as well as drawing molds for natural diamonds.
