Frequently Asked Questions — Gold Bar Casting Solutions

Gold bar casting involves melting pure gold or silver, pouring it into molds under vacuum or inert gas protection, cooling the bars, and finishing them with polishing or stamping for branding and authenticity.

Our casting machines support a wide range, typically from 100 g up to 10 kg bars. The most common are 1 kg, 5 kg, and 10 kg bullion for refineries and investment purposes.

The vacuum system prevents oxidation, reduces porosity, and ensures a smooth mirror-like surface on each gold or silver bar. It also minimizes metal loss during the process.

Yes. The gold bar logo stamping machine can imprint logos, weights, purity, and serial numberswith high precision, helping refiners and banks ensure brand identity and authenticity.

Besides gold, our machines also work with silver, platinum, palladium, and copper alloys, making them suitable for a wide range of precious metal applications.

We provide solutions for both. Small-capacity machines (1–2 kg) are ideal for workshops and labs, while larger systems (5–10 kg per batch or continuous casting) are designed for refineries and industrial-scale production.

With PID temperature control and precision molds, the weight deviation is kept within ±0.001%, ensuring compliance with international bullion standards.

We offer installation guidance, training, technical support, and spare parts supply. Our engineers can also provide customized solutions to meet specific production needs.
