Topcast TVC-XL-G furnaces are used to produce high quality metal grains in a protective atmosphere of Argon or Nitrogen. Process begins with the loading of the precious metal in the crucible; then you can see the display showing process variables. Then the charge is melted by induction heating. Then the shutter is raised and metal is poured into water. After the pouring phase, a flashing alerts the operator that a cycle is over: the grains can be removed and dried.
