Application Introduction
- Cold – working Die Manufacturing
- Stamping Dies: It is suitable for manufacturing stamping dies for various metal materials, such as those used in the stamping process of auto parts and electronic components. Its high hardness and wear resistance can ensure that the die maintains a sharp edge and precise dimensions during long – term and high – frequency stamping, thus improving the quality and production efficiency of stamped parts.
- Cold – heading Dies: In the cold – heading process, SKD11 can be used to make cold – heading dies for fasteners like bolts and nuts. It can withstand the high pressure and friction during cold – heading and extend the service life of the die.
- Cold – extrusion Dies: It is used to manufacture cold – extrusion dies of various shapes, such as those for the cold – extrusion forming of pipes and profiles. Its good toughness and wear resistance enable the die to maintain stability and good toughness and wear resistance enable the die to maintain stability and precision during the cold – extrusion process.
