Core Applications

Why Carbon Graphite?

  • High Temperature Resistance — Withstands up to 2500°C in inert atmosphere, ideal for glass and metal moulding
  • Self-Lubricating — Low friction coefficient (0.05-0.15) reduces sticking and improves release
  • Thermal Stability — Near-zero thermal expansion ensures dimensional accuracy
  • Chemical Resistance — Stable against acids, alkalis, and molten metals
  • Easy Machining — 5-axis CNC compatible for complex geometries
