Abstract (en)

A raw pressure casting in non-ferrous alloys containing material allowances as structural elements has, according to the invention, at least one excess overflow designed to evacuate gases and impurities from the mould without connecting it with the atmosphere. The excess overflow has a form of a flat-wall membrane (2) fitted inside a casting sleeve constituting the central hole (3) and/or a peripheral overflow (4) permanently fixed to the wall of the central hole (3). The method of producing the raw pressure casting in non-ferrous alloys wherein material allowances are applied is, according to the invention, characterized in that at least one material allowance is applied in a form of an excess overflow designed to evacuate gases and impurities from the mould without connecting it with the atmosphere.
