Graphite molds are widely used for high-temperature forming and sintering processes. Made of high-purity graphite material, they feature outstanding thermal stability, low thermal expansion and excellent thermal-shock resistance. Boasting good heat conductivity, high mechanical strength and superior oxidation resistance, they withstand repeated high-temperature cycles. Easy-to-machine for custom sizes and complex structures, they deliver stable performance and long service life, ideal for metal casting, sintering and hot-pressing across multiple industrial applications.
