Gold Silver Graphite Ingot Mold

This is a set of semicircular groove graphite ingot molds, which are widely used in casting precious metals such as gold and silver. Its application is mainly determined by its excellent characteristics, as follows:
High temperature resistance of graphite ingot molds. The melting point of graphite molds is as high as 3650°C, which is far higher than the melting points of metals such as gold (1064°C) and silver (961°C), and it can maintain structural stability at high temperatures and is not easy to deform or melt.
Excellent thermal conductivity of graphite ingot molds. The high thermal conductivity of graphite molds can ensure that heat can be quickly and evenly conducted, making the cooling and solidification of the metal solution more uniform, thereby reducing internal defects and improving the quality of the ingot.
Chemical inertness of graphite ingot molds. This feature prevents it from chemically reacting with precious metals such as gold and silver at high temperatures, avoiding the incorporation of impurities, thereby ensuring the purity of precious metals such as gold and silver.
