6 IN 1 Graphite Ingot Mold for Gold Bar Round Coin

The 6 IN 1 graphite ingot mold is a versatile, professional tool engineered for casting gold bars and round coins. Crafted from high-purity, dense graphite via precision machining, it integrates 6 distinct cavities to produce multiple gold bar sizes and round coin specifications in one tool.

Key traits include excellent thermal conductivity for uniform cooling—ensuring consistent metal structure and sharp detail replication—and a non-stick surface for easy demolding, preserving flawless finishes. It resists thermal shock, withstanding repeated high-temperature cycles without cracking, and minimizes impurity leaching to safeguard gold purity.

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