5 IN 1 Graphite Ingot Mold for Gold Bar Round Coin

The 5 IN 1 graphite ingot mold is a multi-functional, specialized tool engineered for casting gold bars and round coins. Crafted from high-purity, dense graphite via precision machining, it integrates 5 distinct cavities to produce various gold bar sizes and round coin specifications in one tool.

Key traits include exceptional thermal conductivity for uniform cooling—ensuring consistent metal structure and sharp detail replication—and a non-stick surface that enables easy demolding, preserving flawless finishes on bars/coins. It boasts strong thermal shock resistance, withstanding repeated high-temperature cycles without cracking, and minimal impurity leaching to safeguard gold purity.

Ideal for small-scale refineries, jewelry studios, precious metal workshops, and hobbyists. Its all-in-one design eliminates the need for multiple single-cavity molds, saving space and time. Durable, reusable, and precise, it boosts casting efficiency while ensuring professional-grade quality for both functional gold bars and collectible round coins.
