Graphite dies for copper continuous casting are core forming components specifically engineered for the continuous casting process of copper and copper alloys. As a critical interface between molten copper and the final semi-finished product, these dies serve to precisely shape molten copper and facilitate its rapid yet uniform solidification by transferring heat efficiently. Unlike generic molds, they are tailored to withstand the extreme thermal shock and chemical environment of copper casting, ensuring consistent production of high-quality copper billets, rods, tubes, or strips with stable dimensions and surface finish. 


  • Prevents uneven solidification and surface defects in copper products.

  • Optimized pore structure ensures consistent heat dissipation, reducing cracks or blowholes.

  • Proprietary impregnation technology minimizes graphite oxidation at high temperatures, extending die life by up to 40% compared to standard grades.

  • Dense, fine-grained structure reduces lubricant penetration, ensuring stable casting speed and reducing lubricant consumption.

  • CNC-machined for smooth copper release, minimizing drag marks and surface tears.

  • Specialized surface treatment prevents metal sticking, reducing cleaning frequency and downtime.
