Products Description

Vacuum pressurized high temperature copper platinum bullion casting device

CDOCAST vacuum gold bar machine is specially designed for casting high quality gold and silver bar ingots. This machine for making gold bars can melt 4 x 1 kg of gold and silver ingots in each batch. Or up to 1 piece of 15kg gold bar per batch and other custom size gold bars can also be cast in our furnace. The whole melting process takes place under the protection of vacuum and argon gas. The molten ingot has a glossy surface and no water waves.The entire vacuum smelting and casting process minimizes the loss of precious metals and maximizes the protection against metal oxidation.

Application

Feature

1: Our Vacuum gold bar casting machine comes with the plc touch screen system control, the operator only has to filled in the graphite mould with the pre-weighted raw material, like gold powder, gold grain, close the door of the melting chamber as well as press the START switch to release the automatic cycle, the casting will started automaticly, after finished the casting cycle, you can abtain the gold or silver bar which is ready for the market.
2:The induction coil of the vacuum gold bar making machine is custom designed to be either square or rectangular in shape, with a water cooling plate in the middle of the coil. After melting, the cooling plate will be jacked up by a cylinder to rapidly cool the graphite mould, allowing the graphite cover and graphite mould to reach the same temperature, resulting in a bright and flat surface.
3:The entire casting process consists of melting and cooling process, with melting times ranging from 6 to 12 minutes, depending on the size of the bars The cooling time is usually recommended to be 8 minutes or more, as this will maximise the lifetime of the graphite mould.
4:24-hour continuous operation, thus satisfying customers with high production output requirements.
5:There is no need for engineers to install and debug onsite. Each gold bar casting machine comes with installation and debugging video. Under the video guidance, you can simply complete the installation and start to run our furnace,what is more,each vacuum gold bar making machine produced by CDOCAST will be strictly tested before leaving the factory to ensure stable quality Catalog
