Cold Heading Dies

Home/Cold Heading Dies

Cold heading dies also called tungsten carbide punching, cold forming dies, or heading dies. It is compressed by powder metallurgy, with high hardness, high-strength cemented carbide dies, as an important working component of cold heading machine, completes punching, bending, stretching, etc., is widely used in the field of production and processing.

UKO’s cold heading dies have good anti-polishing toughness, fracture toughness, fatigue strength, anti-bending strength, and good wear resistance.

Production process and process of the cold head die
The cold head dies are subjected to a strong stamping load, and the surface of the concave dies is highly compressed, requiring the material of the die to have high strength, toughness, and wear resistance, so the production process and process of the cold die directly affect the quality of the dies.

UKO has many years of tungsten carbide dies manufacturing experience, has accumulated rich technology, from raw materials from tungsten carbide powder to the final product, with a complete set of reasonable, rigorous production technology and quality control processes.

  1. Grinding
  2. Pressing
  3. Sintering
  4. Quality Testing

Appliations of cold head cold diesThe cold head cold dies is mainly used in: a variety of metals and non-metallic powders, stamping, steel rods, steel pipe stretching, large stress, working, perforation and stamping mold, machine accessories, Core, making stamping mold, such as stamping watch parts, musical instrument spring, etc.

Why is tungsten carbide cold heading die performance better?2021-04-14T07:33:45+00:00

In the standard parts industry, tungsten carbide cold heading dies to need to under great unit pressure in cold upsetting deformation process, when a large degree of deformation and material hardness, units of pressure up to 2000MPa more.

At the same time the metal flow intense, thus requiring tungsten carbide cold heading dies to have high strength, high hardness, and good fatigue resistance, in order to ensure the cold heading dies under high pressure without breaking, deformation, and wear resistance. Tungsten carbide cold heading dies raw material is produced by powder metallurgy composite materials, which have high hardness, wear resistance, life is several times and several hundred times than ordinary cold heading die.

With carbide manufacturing standard tungsten carbide cold heading die, not only have high dimensional accuracy of parts but also greatly improve the life of the cold heading die, can create good economic and social benefits.
