Abstract (en)
A vacuum die-casting method for producing castings of nonferrous alloys, comprising the steps of: keeping a material of nonferrous alloy in a molten state in a holding furnace (11); transferring a preset amount of material from the furnace (11) to a die (18), at injectors; compressing the material in the die and allowing it to cool. The material, during the various steps, is continuously protected from contact with air, in regions not occupied by containment elements, by an atmosphere of gas which protects from contaminations and from the danger of oxidation, the gas having a higher relative density than air. <IMAGE>
