Cold Heading Die Core Nut Die

The cold heading die bears the heavy pressing load, and its female die surface bears high-pressure stress so that the die core material is required to have high strength, toughness and wear resistance, tungsten carbide with high cobalt content(Most grades applied to the heading die core contains cobalt more than 12%, some even reach up to 25%) can perfectly meet this requirement, so all better heading die with long service time use tungsten carbide as die core material, and the outer case of the die is made of hot working die steel (the hardness after heat treatment is about HRC 45). The core is inserted the outer case the core by cold pressing or hot pressing method, so as to make the core and case combine closely, and the outer case causes certain compressive stress to the inner core, which improves the service conditions of the die and extends the service life time of the die.
