Graphite Ingot Mold with Lids

The Different Size Graphite Ingot Mold with Lids is a professional, versatile tool engineered for precision metal casting. Crafted from high-purity, dense graphite via precision machining, it offers a range of customizable sizes to match diverse casting needs—from small-batch precious metal ingots to larger alloy bars.

Key traits include the integrated lid, which retains heat for uniform metal solidification, prevents gas escape and impurity intrusion, and safeguards molten metal from oxidation. The molds boast exceptional thermal conductivity for consistent cooling, a non-stick surface for easy demolding, and robust thermal shock resistance to withstand repeated high-temperature cycles without cracking.

Ideal for small refineries (precious metal processing), jewelry studios (gold/silver ingot casting), and materials labs (alloy R&D). Their size flexibility eliminates the need for multiple single-size molds, while the lids enhance casting quality by ensuring flawless, pure ingots. Durable, reusable, and compatible with copper, aluminum, and alloys, they balance efficiency and precision for both industrial and craft scenarios.
