Nelyrho 4 Pieces 1kg Graphite Ingot Molds
This set includes four identical 1kg graphite ingot molds, crafted from high-density fine-grained graphite (99.9%). These molds are designed to minimize sticking and facilitate easy release, especially after turning the mold upside down and tapping. They are well-suited for refining gold, silver, copper, aluminum, and brass. The durable material helps maintain shape under high temperatures and provides consistent results for small-scale casting projects.
MMasters 4-Round Premium Graphite Ingot Mold
Designed with four round cavities, this premium graphite ingot mold offers precise size control and reliable release. Outer dimensions are 3.74 x 3.74 inches with a shallow 0.55-inch depth. Each cavity can hold up to approximately 190 grams of gold or 103 grams of silver, making it suitable for small to mid-sized casting runs. The graphite construction ensures high-temperature stability and maintains metal purity with minimal ash content, supporting accurate melting and pouring workflows.
Nelyrho 8-in-1 Metal Casting Kit
This all-in-one kit provides a comprehensive setup for gold refining and metal pouring. It includes a 5-in-1 ingot mold, a 1kg ingot mold, two graphite stirring rods, a quartz cup, a graphite crucible, and crucible tongs. Both graphite and quartz components are engineered to withstand high temperatures and thermal shocks, enabling precise melting, refining, and pouring with minimal metal loss or contamination. It is ideal for jewelers, hobbyists, and small-scale refining operations seeking a complete, torpedo-ready solution.
OTOOLWORLD Long Strip Graphite Ingot Mold
This long-strip graphite mold variant offers flexible sizing to fit different melt outputs. It is designed for gold and silver casting after pouring, with the ability to select from listed sizes. The elongated cavities enable batch processing and efficient workflow for projects requiring longer, uniform ingots. The graphite composition provides excellent heat resistance and smooth demolding for consistent results.
Graphite Mold Lady Ingot Mold
This graphite mold variant is marketed for 3D image casting and supports metals such as gold, silver, copper, aluminum, and tin, as well as potential glass pressing. It emphasizes high-quality graphite with reliable heat tolerance, offering a versatile option for creative casting projects beyond standard ingots. The design aims to balance ease of release with durability for repeated use in metal processing tasks.
MMasters 0.5kg Premium Graphite Ingot Mold
This compact 0.5kg graphite ingot mold measures 2.71 x 1.73 x 0.87 inches externally with an inner size of 2.24 x 1.26 x 0.63 inches. It holds up to 500 grams of gold or 265 grams of silver and is made from premium graphite with low ash to preserve metal purity. Ideal for small, precise melting and pouring tasks—especially for hobbyists and labs focusing on small-scale metal processing and refinement.
Buying Guide: Key Purchase Considerations
- Material and purity: Graphite molds offer high-temperature tolerance and minimal ash contamination, preserving metal purity during melting and pouring.
- Capacity and cavity count: Choose molds with the appropriate volume for your typical ingots (e.g., 190 g to 1 kg) and whether you need single or multi-cavity designs for batch runs.
- Heat resistance and durability: Look for molds rated to withstand temperatures up to 1800°C (3272°F) or higher if you’re refining gold and silver; a robust mold reduces warping and sticking.
- Release behavior: Some molds feature slight cavity walls or designed angles to aid demolding; consider whether you prefer easy release or a longer mold life.
- Kit completeness: All-in-one kits with crucibles, tongs, and stirring rods simplify setup for beginners and ensure fewer missing components during refining.
- Compatibility with metals: Ensure the mold supports your target metals (gold, silver, copper, aluminum, brass, etc.) and is suitable for small-scale laboratory or jewelry work.
- Maintenance and cleaning: Graphite molds are generally easy to clean but require careful handling to prevent surface damage that could affect future pours.
- Cost and value: Compare price against capacity and durability to determine the best value for your refining workflow and project scale.
