Vacuum casting machine G 10

THE NEW AND ULTIMATE ALUMINUM LOST-WAX CASTING SYSTEM Managing casting to obtain pieces in aluminum and its alloys free of porosity and impurities. ASEG GALLONI, long since been specialized in lost wax casting, has developed a device that can eliminate porosity and impurities from castings in aluminum and its alloys, suitable for various industrial sectors. Thanks to a special inert gas mixing equipment combined with a vacuum system manufactured by ASEG GALLONI it assures castings featuring a quality that is largely superior to the one achieved with other conventional casting machines. FOR AN UNABLE QUALITY To eliminate hydrogen and any impurity from the cast aluminum bath used to manufacture the industrial castings, ASEG GALLONI, together with an experienced customer has created an innovative system that combines an inert gas mixing device with vacuum. When the aluminum/alloy loaded in the crucible has reached the molten state, two hollow graphite propellers are immersed in the bath, mixing the molten aluminum at a controllable speed and, since they are fitted with small holes, they blow inert gas at the same time. In this way, all the hydrogen and heavy scum present in the bath are made to rise to the surface. Once mixing has been completed the two propellers are extracted and vacuum casting is carried out. Thus scum remains trapped in the sprue which is subsequently cut while the alloy making up the piece is perfectly free of impurities and proposity. “Our customer, with whom we have developed this system- says Gianluca Galloni, company president- works in the aerospace sector, hence it subjects its products to severe quality tests.
