Complete Set, Ready to Use: This kit includes 2 identical 1kg-capacity graphite ingot molds, designed for small-batch metal melting and casting, suitable for continuous or varied projects in labs, jewelry workshops, and hobby applications
Premium High-Purity Graphite Material: Made from high-density, fine-grained premium graphite with extremely low ash content (<0.1%). This ensures metal purity, resists cracking or deforming under high heat, and offers long-lasting durability, withstanding extreme temperatures up to 2000C (3632F)
Precise Dimensions, Standard Ingots: Each mold has outer dimensions of 4.01" x 2.01" x 1.01" and an inner cavity of 3.54" x 1.57" x 0.78". It casts standard rectangular ingots weighing approximately 1kg of gold or 530g of silver, ensuring accurate and uniform results
Excellent Thermal Conductivity & Easy Release: The superior thermal conductivity of graphite significantly reduces melting time and saves energy. Its natural self-lubricating properties allow for effortless ingot release; simply tap the mold to obtain smooth, non-stick metal ingots, enhancing your casting experience
Versatile for Wide-Range Applications: This versatile mold set is suitable for melting and casting various non-ferrous metals including gold, silver, aluminum, copper, and brass. It reliably serves purposes from precious metal recovery and jewelry making to metal experiments and small-scale foundry work
Robust Construction for Repeated Use: The molds feature excellent thermal stability and structural strength, capable of withstanding repeated thermal shocks from molten metal without deforming or cracking, ensuring reliable performance over extended periods of use
Safe Storage and Maintenance: Keep the molds dry and clean before and after use, and store in a cool place. Proper preheating before first use is recommended to remove any potential moisture and ensure optimal casting performance
