Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a casting process for making metallic components, along with a casting device. The process involves preparing a metal melt, moving it into a dosing chamber set under vacuum, and then pushing it into a mold cavity using pressurized gas. The innovation is that the pressure applied to move the melt comes only from the gas atmosphere within the dosing chamber.

Use CasesContent extracted from patent full text and abstract with AI.

  • Manufacturing automotive parts with precise and complex shapes
  • Producing aerospace components requiring high strength and quality
  • Making industrial machine parts with consistent properties
  • Creating electronic housings or casings from metal
  • Large-scale casting of metallic structural components

BenefitsContent extracted from patent full text and abstract with AI.

  • Improved control over the filling of the mold, leading to better part quality
  • Reduced risk of contamination, since the melt is moved by gas atmosphere only
  • Ability to manufacture more complex shapes with fewer defects
  • Potential for higher efficiency and automation in metal casting processes
  • Enhanced mechanical properties due to controlled casting conditions

Patent Abstract

Das erfindungsgemäße Gießverfahren zur Herstellung eines metallischen Bauteils (16) weist die Schritte (S1-S5) auf:- eine Metallschmelze (12) in einem Schmelzeraum (4) bereitstellen,- eine Dosierkammer (10), die einer Werkzeugkavität (14) fluidführungstechnisch vorgeschaltet und dem Schmelzeraum (4) nachgeschaltet ist, gegenüber dem Schmelzeraum (4) unter Unterdruck setzen,- in die Dosierkammer (10) unter Wirkung des Unterdrucks zumindest einen Teil der Metallschmelze (12) einleiten, und- die Dosierkammer (10) mit einem Überdruck beaufschlagen, wobei die Metallschmelze (12) die Werkzeugkavität (14) füllt.Eine Druckvermittlung des Überdrucks auf die Metallschmelze (12) innerhalb der Dosierkammer (10) erfolgt dabei ausschließlich durch die Gasatmosphäre in der Dosierkammer (10).
