The big VCs are mostly used for precise castings in aluminium alloys – the hydrogen content of aluminium alloys may be adjusted by regulating the vacuum during melting. This way, foaming of molten metal can be avoided without any melt additives. Overpressure in the melting chamber during and after casting and simultaneous vacuum in the flask chamber optimise form filling especially in filigree or thin walled areas.
Big VCs are always the first choice for parts with complicated geometry or when the number of pieces are not large enough for die casting production.
The magnesium casting versions are constructed according to strict safety requirements and guarantee safe and easy casting of magnesium – and of course of many other metals too.
