1. High hardness: The mold material should have sufficient hardness to ensure that it will not deform or wear during the punching process.
2. Wear resistance: The mold material should have sufficient wear resistance to ensure that good punching effects can be maintained after long-term use.
3. Corrosion resistance: Since corrosive substances such as electrolyte are involved in the lithium battery tab punching process, the mold material must have sufficient corrosion resistance.
4. High strength: The mold material must have sufficient strength to ensure that it will not break or deform during the punching process.
5. Good thermal conductivity: The mold material should have good thermal conductivity to ensure rapid heat dissipation during operation.e punching process and avoid deformation or damage caused by overheating.
