Feature: 1. Smelting Effect: The hot and cold conditions of the mould crucible are fast, and the thermal stability is good, which can create a delicate refining effect for you. 2. Good Performance: The graphite mold for casting metal has good thermal stability, can withstand 2000 Celsius, shortens the melting time and saves energy. 3. Material: The graphite casting mold is made of graphite material, and the graphite casting mold will not affect the metal purity during the metal refining process. 4. Impact Resistance: Our ingot graphite mould has good impact resistance and acid and alkali corrosion resistance, which is more conducive to metal smelting. 5. Application: The ingot mold has a wide range of applications, suitable for the experiment and smelting of non ferrous metals such as gold, silver, brass, copper, aluminum, zinc, etc. Specification: Item Type: Ingot mold Material: Graphite Product Size: Approx.
