What Is a Cold Heading Die?

The cold heading die is a mold tool for cutting, pre-forming, and forming into cold-formed parts on the blank material on the cold heading machine.

In which areas are hard alloy cold heading dies mainly used?

  • Molding and stamping of various metal and non-metal powders, drawing of steel rods and steel pipes with high compression rate, upsetting, perforating and stamping dies working under greater stress, machine parts, mold cores, and making stamping dies, such as stamping Watch parts, musical instrument springs, etc.;
  • Moulds for making battery shells and toothpaste skins;
  • Small size steel ball, screw, nut stamping dies, impact-resistant forging dies and cold heading, cold punching and cold pressing dies for standard parts, bearings, tools and other industries, such as bullet and bullet shell stamping dies.
  • Cemented carbide is a high-hardness, high-strength alloy material that is pressed and sintered by powder metallurgy. It is widely used in the production and processing field; therefore, the use of cemented carbide as the raw material for cold heading molds can resist impact or strong impact. Under grinding working conditions, it has good impact toughness, fracture toughness, fatigue strength, bending strength and good wear resistance.

How to choose a hard alloy cold heading die?

Cold heading molds require mold materials with high strength, toughness and wear resistance. Usually, medium and high cobalt and medium and coarse grain alloy grades are selected. Therefore, when selecting the cold heading die grade, it is necessary to meet specific requirements according to the processing object and processing working conditions.
