1. Electrical Conductivity: Our melting god features thermal resistance, the electrical conductivity and the thermal conductivity, which can melt metals well.2. Wear Resistance: Our ingot mold has good wear resistance, strong lubricating properties and durability. It also has a long service life and can be used for a long time, leaving you satisfied.3. High Density: Our graphite ingot mold has high purity, high density, high mechanical strength and strong chemical stability. In the process of melting metal there is no chemical reaction with the metal.4. Lubrication: The surface of our graphite crucible can be treated with anti-oxidation. It has high purity, high mechanical strength and good lubricity, so it is more convenient for metal smelting.5. Application: Our cast iron mold can be used for smelting gold, silver and other precious metals, which is very suitable for metal smelting in various factories.Item type: ingot casting toolsgraphite disc size: approx. 50 x 13 mm or 2 x 0.5 inch (diameter x height)Internal dimensions of the disk: approx. 40 x 8 mm or 1.6 x 0.3 in.
