Platinarum Vac

Vacuum induction centrifugal casting machine with MOSFET system.

1.Casting chamber under full vacuum with appropriate inert gas protection (argon or nitrogen).

2.Vacuum removes gases from the invested flask minimizing or eliminating gas porosity and radically enhances crucible life, argon or nitrogen gas         prevents oxidation of gold and platinum alloys.

3.Medium-frequency induction melting with self-stirring effect to ensure absolute homogeneity from the top to the bottom of the cast tree.

4.It melts and casts 350 gr platinum in special ceramic crucibles and 1,5 kg gold (24 kt) in high quality pure graphite crucibles.
