• 【Ample Quantity & Perfect Size】The package includes 4 graphite ingot molds, offering sufficient quantities to meet your daily DIY requirements. With external dimensions of 3.94x1.97x0.98" and internal dimensions of 3.54x1.57x0.79", these molds are meticulously designed to perfectly match the casting needs of 1kg/2.2lbs gold.
• 【High-Purity Graphite Material】Crafted from quality high-purity graphite material, our casting molds have almost no ash content, which won't affect the purity of the metal during the metal refining process. With them, you can enjoy precise and quality results every time.
• 【High-Performance Construction】Boasting good thermal conductivity and heat resistance, the graphite ingot molds can endure high temperatures up to 3632°F, ideal for various metal forging processes. They feature excellent resistance to corrosion, acid, and impact, ensuring reliable performance.
• 【Effortless Release】With its superior self-lubricating properties, our melting refining tools allow for easy release of the cast metal ingots with smooth surfaces without residue. Requiring no preheating and oiling, this effectively simplifies the casting process and enhances the overall output quality.
• 【Versatile Metal Compatibility】These graphite casting molds are ideal for melting and casting various non-ferrous metals such as gold, silver, copper, aluminum, and zinc. With exceptional performance, they serve as the perfect tool for both experimental and industrial production.
