Basic definition and characteristics
Carbon graphite mold is an industrial mold made of graphite as the main material, with the following core characteristics:
High temperature resistance: can withstand high temperatures of 1600℃-3000℃, suitable for metal smelting scenarios
Thermal stability: low thermal expansion coefficient (0.5-4.5×10⁻⁶/℃) and excellent thermal shock resistance
Self-lubricating: reduce demoulding resistance and improve the surface finish of castings
Main application areas
Metal casting
Uniform crystallization during continuous casting of copper/aluminum alloys, reducing the scrap rate by more than 30%
Centrifugal casting of bronze sleeves (US case, wall thickness ≥25mm)
Precious metal processing
Customized small molds for gold and silver purification (1#-60# specifications)
Special industries
Fuel cell bipolar plate molding
Heating/support components for diamond tool sintering
Technical parameter comparison
| parameter | Ordinary graphite mold | Silicon carbide composite |
|---|---|---|
| Density(g/cm³) | 1.6-1.8 | 2.0-2.2 |
| Compressive strength(MPa) | 35-80 | 90-150 |
| Applicable temperature (℃) | ≤1600 | ≤2200 |
| Lifespan (times) | 200-500 | 800-1200 |
Special process improvement
Through surface treatment technology (such as conversion into silicon carbide or boron carbide layer), the mold’s wear resistance can be enhanced and its service life can be extended by 3-5 times. Currently, 97% of the market demand is for graphite-silicon carbide composite molds.
