Gold Melting Graphite Mould

Gold melting graphite mould - a key tool in the gold smelting process. Its use has brought many conveniences to the gold smelting industry:

Graphite moulds are resistant to high temperatures and have stable performance. They can withstand temperatures of up to 3000℃, can withstand high temperatures of about 1000℃ in the gold melting process, and can be used for a long time without deformation. At the same time, the thermal expansion coefficient of graphite moulds is low, which can ensure the stability of mold dimensions and the accuracy of castings.

Compared with traditional metal molds, graphite moulds have faster heat conduction, which helps to shorten the gold melting time. And the uniform thermal conductivity of graphite moulds can reduce local overheating, thereby reducing energy consumption.

During the gold melting process, the chemical inertness of graphite moulds prevents them from reacting with gold at high temperatures, ensuring the purity of the finished gold product, which is particularly important for high-purity gold bars and precision jewelry casting.

Graphite moulds can be processed into any form (such as complex flow channel structures), support lost wax casting, vacuum casting and other processes, and can meet the needs of personalized jewelry customization. Its surface finish reduces the subsequent polishing process for casters.

From the perspective of economic benefits, graphite moulds can be reused many times, which can significantly reduce costs compared to steel molds. In addition, graphite moulds are easy to demould, and combined with automated production lines, they can achieve a daily production efficiency of 10,000 pieces.
