Key features

• •Complete Set, Ready to Use: This kit includes 4 identical 1kg-capacity graphite ingot molds, designed for small-batch metal melting and casting, suitable for labs, jewelry workshops, and hobbyists
• •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
• •Batch Production Capability: Four identical molds enable simultaneous processing of multiple metal projects or batch production, increasing efficiency and productivity for continuous casting operations
