High-quality Materials: Coin mold is made of high-quality high-purity graphite with an ash content below 0.1%, performing exceptionally well under high temperatures, highly durable, and stable without breaking or deforming. It ensures no impurities during the casting process, protects precious metal purity, and enables efficient and stable casting
High-efficiency Function: Graphite coin mold features outstanding heat performance and good thermal conductivity, can withstand high temperatures up to 2000°C, remains stable during rapid heating and cooling, shortens melting time and reduces energy consumption, and is suitable for refining gold, silver, copper, aluminum and other metals
Perfect Demolding: Metal casting molds' mold features a smooth inner wall and excellent self-lubricating properties, allowing smooth and non-stick demolding with no residue for quick ingot removal, making it ideal for jewelry making and metal refining enthusiasts
Packaging Includes: Industrial metal casting molds measures 3.74 x 3.74 x 0.55 inches, with an inner diameter of 1.57 inches and a depth of 0.31 inches. Each cavity can hold up to 190g of gold or 103g of silver. Please confirm the required size carefully before placing your order
Widespread Application: Silver molds casting can melt and analyze non-ferrous metals including gold, silver, copper and aluminum, and is widely used in high-precision laboratory analysis, precision jewelry casting, industrial metal processing, small-scale metallurgical experiments and other fields, making it an ideal tool combining professional efficiency and convenient operation
