Dimensions and Capacity: The external dimensions of this graphite molds for casting metal are 2.75 x 2.63 x 1.02 inches; Internal dimensions: 1.98 x 1.86 x 0.66 inches. It can hold up to 500 grams of gold or 265 grams of silver, with a volume of 0.98 fluid ounces, enabling precise measurement, melting, and casting of metal ingots
High-Quality Materials: This metal mold is made from premium-grade graphite, with ash content controlled to less than 0.1%. It maintains structural stability under sustained high temperatures, withstand fracturing and deformation, and effectively prevents impurities from entering the molten metal, thereby preserving the metal's original purity
Thermal Conductivity: This silver mold offers excellent heat transfer efficiency, significantly shortening smelting cycles and reducing energy waste. It can reliably withstand extreme temperatures of up to 1800°C (3272°F) without any decline in performance
Easy Demolding: Thanks to casting molds's inherent self-lubricating properties, solidified metal ingots slide out smoothly and completely after cooling, leaving no metal residue in the cavity, which facilitates post-use cleaning
Wide Compatibility: This casting ingot mold can be widely used for smelting and refining various non-ferrous metals, including gold, silver, copper, and aluminum. It is ideal for laboratory analysis, handmade jewelry making, and small-batch metal smelting, offering exceptional flexibility
