Melting under vacuum conditions enables slag-free melting and riddance of unwanted dissolved gasses and elements. The VIM system has a small (for 5kg) coil in addition to the large (for 10kg) one, ...

Resistance heating is commonly used with aluminum and copper alloys. Vacuum induction melting (VIM) uses an induction heating source within a sealed, air-evacuated chamber. Often, crucibles that ...
