Feature: 1. Thermal Conductivity: Our casting ingot mold has thermal shock resistance, electrical conductivity and thermal conductivity, which can smelt metals well and you will be satisfied. 2. Lubricating Properties: Our melting ingot has good wear resistance, strong lubricating properties and durability. It also has long service life, and can be used for a long time. 3. High Purity: Our ingot mold has high purity, high density, high mechanical strength and strong chemical stability, so in the process of metal smelting, there will be no chemical reaction with any metal. 4. High Mechanical Strength: The surface of our mould crucible can be treated with anti oxidation. It has high purity, high mechanical strength and good lubricity, therefore it is more convenient for metal casting. 5. Applicable: Our graphite casting mold can be used for smelting metals such as gold and silver, so they are very suitable for smelting metals in various factories and experiment.
