What are the characteristics of cemented carbide drawing die

       The choice of mold material determines the characteristics of the mold. When processing soft materials, you can choose to use a cemented carbide drawing die. Why choose cemented carbide material, what are the characteristics of cemented carbide drawing die? Let me tell you about it.

   High abrasion resistance. The hard alloy die material has high wear resistance, which can ensure that the drawing die can work for a long time under any degree of deformation, and the size of the drawing part remains unchanged.

Excellent polishability. Cemented carbide has good polishability and can be processed into a die hole with a mirror finish to ensure the high quality of the surface of the drawn part.



   Low adhesion to stretched metals. During the drawing process, the ferrous metal material has little adhesion to the cemented carbide die material, which ensures that the cemented carbide drawing die has a long life.



   The coefficient of friction is small. When using the cemented carbide die for drawing, the friction coefficient between the ferrous metal material and the cemented carbide die is small, and the energy consumption is small.



   High thermal conductivity. Due to the high thermal conductivity of the cemented carbide mold material, the heat generated during the stretching process can be quickly conducted away, which improves the durability of the mold.



   Good corrosion resistance. Due to the above characteristics of cemented carbide mold materials, when drawing, the mold life is long, the production efficiency is high, and the scrap rate of the drawn parts is low, which can greatly reduce the production cost. The life of cemented carbide molds is more than ten times, or even dozens of times longer than molds made of other alloy tool steels.
