Molded graphite

1. Molded graphite High density / Fine grain size / High purity / High strength / Low specific resistance / Ease of precise machining
2. Excellent thermal shock resistance to high temperature and oxidation / Good anticorrosion

• Semiconductor (Monocrystalline Silicon) / Vacuum furnace / Continuous casting / Sealing products / Space & medical industry / Forge moulds EDM.
• Heaters / Heat shields /Electronic tube anodes / Melting and sinteringmoulds for Pottery & Electronic Products & Cemented Carbide & Diamond & Aluminium & Copper & Other metals/ Etc.
