The carbide wire drawing dies adopt high-quality tungsten carbide as the core, which has high hardness, good thermal conductivity and low friction coefficient. Tungsten carbide wire drawing dies are simple to produce with corrosion-resistant, impact-resistant, and low cost which is the outstanding feature of this product. It is suitable for the drawing of ferrous metals, large-size wires, and occasions with poor wire drawing conditions.
The Brands And Applications Of Tungsten Carbide Wire Drawing Dies

Why The Tungsten Carbide Wire Drawing Dies Are Durable
When adopting high function and high-speed molds for production, the mold is required to have a long service life. In recent years, high-precision and high reliability are required even if for a small amount of production. Carbide dies with high durability will be the best choice.
Tungsten carbide wire drawing dies have the following features which ensure the high durability
1. Strong power resistance
The mold should be given a very large extrusion, bending stress, impact and other messy loads during the extrusion process. Therefore, the material selected will have high power resistance after heat treatment. The mold material should have outstanding hardenability to ensure that the mold can be hardened and uniform.
2.Excellent wear resistance
The mold should have high wear resistance to ensure normal service life and produce large quantities of extruded parts. In general, the hardness of steel is proportional to wear resistance under certain conditions. Therefore, mold materials must have sufficient hardenability. In addition to the hardness, The decisive factors are the thickness, composition, amount of excess for the matrix after heat treatment and the amount, size, type, dispersion, red hardness of carbide. The tungsten carbide has a content of more than 80% of WC, the wear resistance of which is several times higher than steel. So to get a long service life for the drawing mold, and carbide is mostly adopted for the materials.
3.Sufficient thermal stability
For continuous production, the temperature of the mold sometimes will reach 200 ° C, which will reduce the strength and hardness, so that the mold material should have outstanding thermal stability. Carbide drawing dies have sufficient thermal stability for high-temperature resistance.
4.Excellent processability
Cold extrusion mold has a long manufacturing time with high accuracy requirements. Usually, it is necessary to cast, cutting, heat treatment, grinding or other fine finishing. So only the materials that have good processability can meet the production needs. The excellent process of carbide molds will be the best choice.
The Precautions And Maintenance Of Tungsten Carbide Wire Drawing Dies
1. Ensure the stability of the drawing machine
Each drawing drum, over-line guides should be smooth, flexible, strictly controlled for beating tolerance. If the drum is found, the guide wheel has a worn trench and the drawing dies should be repaired in time.
2.Good lubrication
Good lubrication is important to ensure the surface quality of the wire and extend the service life of the mold. The lubrication index should be checked frequently, removing the copper powder, impurities in the lubricant, so that the equipment hole can not be polluted. If the lubrication doesn’t work, it must be replaced in time and clean it.
3. Reasonable allotype
Reasonable allotype is to ensure the surface quality of the wire and control size accuracy, reducing the wear of wire drawing drum and equipment operating load. For sliding wire drawing machines, it is necessary to familiarize with the mechanical elongation of the equipment. The sliding coefficient is reasonably selected, which is the primary step of fitting mold.
4. Appropriate adjustment of the size for the compression angle
The surface reduction rate of each drawing and the material of the drawn wire are also closely correlated with the compression angle of the respective mold. The size of the compression angle is appropriately adjusted according to the size of the surface reduction rate.
5.The timely replacement of the aging drawing dies
When the drawing die reaches the service life, please replace it in time for repairing treatment to avoid excessive causing scrap the wire.
Summary
The tungsten carbide wire drawing dies are widely used for drawing in various industries. It has high hardness, excellent thermal stability, high durability and long service life and is one of the best mold materials.
