Zero Defects

Pressovac Max XL: multiple alloy casting machine by Aseg Galloni Spa


The system used by Pressovac series casting machines was specially developped for dental labs where casting perfection is absolute: casting pieces have a very smooth surface, a very dense molecular structure and without defects like unproper filling, porosity and shrinkage. Just by pushing a button, the whole crucible/ flask system will automatically rotate 90° and the metal, once poured in an homogeneous and controlled way into the flask, it is automatically pressurized to 4 bars by argon gas. This high and quick pressurization is indispensable to obtain a proper and homogeneous filling, even at low metal/flask temperatures, for gold, silver and bronze alloys and, above all, for platinum and special steels which have a very narrow melting interval, thus a very quick solidification. This results in a very smooth surface due to the effect of the vacuum and a dense, well compacted casting due to the "over pressure” of 4 bars, which benefits both thick and thin sections. This XL model is particularly suitable for large stainless-steel casting as well as for manufacturing Pt ingot up to 2 kg.
