The Heart technology of our Gold silver Ingot Vacuum casting machine is the induction generator and induction coil, we design them to maximize the heat transfer during the Casting cycle and the induction coil is designed as a square shape which 100% matches the shape of the Graphite mold which can guarantee the Casting Process heat distribution is uniform,
COOLDO Gold Vacuum Casting Machine is designed to produce Different dimension of gold&silver ingots from 100 g to 15 kilo. You just need to put the pre-weighted gold/silver grains or powder into our custom-designed graphite mold, and then positioned it inside the Vacuum Casting chamber, the casting time will take about 10mins and cooling will take about another 10mins,
Our vacuum gold Silver bar making machine is totally designed as an automatic casting machine, the operator only has to fill in the graphite mold with the pre-weighted raw material, like gold&silver grains, and then 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.
During the whole casting process, the whole Casting and cooling down process will take place in a closed vacuum chamber, we have designed an automatic program that can vacuum the melting chamber automatically, you just press the Vacuum button and then the vacuum process will be automatically done within 5 minutes, what is more, inert gas like Argon or Nitrogen will be filled in the melting chamber which can prevent the silver or gold from Oxidation.
