Nelyrho 100 oz Cast Iron Loaf Bar Ingot Mold
The Nelyrho mold is crafted in cast iron and supports up to 100 troy ounces, suitable for melting and refining non-ferrous metals such as gold, silver, copper, and aluminum. Its design emphasizes high temperature resistance and robust thermal conductivity, helping to produce uniform ingots. The wide application includes use as a graphite crucible substitute or for straightforward ingot formation, making it a versatile choice for hobbyists and small foundries.
Bonbo 100 Oz Cast Iron Ingot Mold For Gold And More
This 100-ounce loaf mold is designed for gold, silver, copper, aluminum, brass, and other metals. Its upgrade handle aids safer pouring and handling, and tapered side walls facilitate easier removal of the finished bar. The inside cavity is not polished like graphite molds, but turning the mold over releases the ingot efficiently, minimizing sticking and improving workflow in castings and refinings.
Nelyrho Graphite Ingot Molds (4 Pieces, 1kg Each)
This set contains four 1kg graphite ingot molds made from high-density, 99.9% graphite. Graphite molds offer excellent heat resistance and longer-term durability, making them well-suited for refining and casting of gold, silver, aluminum, copper, and brass. The design emphasizes easy release of ingots without sticking, especially when used with compatible fluxes and seasoned handling.
MMasters 4-Round Graphite Ingot Mold
Featuring four graphite cavities, this mold is designed for precise melting and casting of gold, silver, copper, and aluminum. Made from premium graphite with minimal ash, it maintains metal purity and resists high temperatures. It is well-suited for laboratories, jewelry making, and metal processing, offering reliable performance and clean ingot releases.
MMasters 4kg Premium Graphite Ingot Mold
This larger graphite ingot mold holds up to 4 kg of gold or 2.12 kg of silver, with inner cavities sized to optimize molten metal flow. Graphite’s low ash content helps preserve metal purity, and the mold is designed for durability under repeated heating cycles. Suitable for factories, studios, and advanced hobby setups handling substantial metal volumes.
Layhit Graphite Casting Ingot Molds (6 Pcs)
Layhit offers a six-piece graphite set designed for melting and refining gold, silver, copper, and brass. Graphite’s heat conduction helps reduce melting times, while resistance to acids, corrosion, and high temperatures ensures reliable performance in demanding metal processing environments. Ideal for laboratories and jewelry production workflows requiring multiple molds.
Buying Guide: Key Considerations For Molds In Metal Casting
When selecting ingot or mold tooling, consider material, capacity, heat resistance, ease of release, and compatibility with your metals. Cast iron molds provide durability and higher heat tolerance, but graphite molds excel in heat distribution and easy release, reducing sticking. Graphite variants are best for precious metals where purity and clean pour are essential. For larger batches, higher-capacity graphite or graphite-coated options offer efficiency, while multi-cavity designs can speed up production. Always ensure proper ventilation and safety gear when melting metals and handling hot molds.
Capacity and dimensions should align with your target ingot size and workflow. If you refine a mix of metals, a versatile graphite mold with multiple cavities or a set of molds in different sizes can support flexibility. Durability under repeated heating cycles is crucial for long-term use; look for high-quality graphite with low ash content and cast iron with robust thermal conductivity. Finally, verify that handles and design features enhance control during pouring to minimize spills and injuries.
For beginners, starting with a small or mid-size graphite ingot mold set helps learn the process without committing to large batches. For experienced foundry workers, higher-capacity graphite molds or sturdy cast iron loaves offer efficiency and reliability under demanding casting conditions. Evaluating these factors will help you choose a mold that aligns with your material, throughput, and safety needs.
