1: Our Vacuum gold bar casting machine comes with the plc touch screen system control, the operator only has to fill in the graphite mold with the pre-weighted raw material, like gold powder, and gold grain, close the door of the melting chamber as well as press the START switch to release the automatic cycle, the casting will start automatically, after finished the casting cycle, you can obtain 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 mold, allowing the graphite cover and graphite mold to reach the same temperature, resulting in a bright and flat surface.
3:The entire casting process consists of a 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 maximize the lifetime of the graphite mold.
4:24-hour continuous operation, thus satisfying customers with high production output requirements.
