Cold heading mold is so important, do you really know?

Cold heading mold is so important, do you really know?

Many fasteners are formed by cold heading die. The cold heading die (injection mold making) is subjected to severe stamping load, and the die face is subjected to very high compressive stress. Mold material is required to have high strength, toughness and wear resistance. 



Cold heading die (tekanan die casting Mesin) must have high hardness after heat treatment, and the core must have good toughness, so that the surface has a certain compressive stress can offset the stress during the cold heading process.
Cold work die steel includes punching die (mold maker china), blanking die, trimming die, punch and scissors, cold heading die and cold extruding die, bending die and drawing die, etc.. 

Cold working die steel at work, due to the deformation resistance of the material is relatively large, the work of the mold to bear a lot of pressure, bending force, impact force and friction. Therefore, the cold die normal scrap reason is generally wear and tear. Failure due to fracture, collapse and deformation is premature. 



Compared to cold die steel and tool steel. There are many things in common. Requirements of the mold with high hardness and wear resistance, high bending strength and sufficient toughness to ensure the smooth progress of stamping process, the difference is that the mold shape and I process complex. Therefore, the requirements of higher wear resistance mold, work under great pressure. Because of its complex shape and easy stress concentration, it requires high toughness, large size and complex shape. Therefore, higher hardenability, smaller deformation and cracking tendency are required.
