Optimization of the production of metal products Cast

A method for optimizing cycle time and / or casting quality in the production of an article of cast metal that has been defined by a CAD product model. The method comprises the steps of DOLLAR A (A) providing a computer-casting model using objective functions that simulate the filling and solidification of the CAD product model within pressure casting molds, the casting model is divided into adjacent portions, each portion terms in at least has one of the objective functions for thermal conductivity, heat capacity, and the cooling time, DOLLAR a (B) occupying the objective function terms with experimental data for calibrating the casting model, deriving tuned heat transfer coefficients for each area and simulating the filling and solidification of the product within the pressure casting molds and DOLLAR a (C) maintaining the objective functions in order to ensure a directional solidification along the series of adjacent sections, while the thermal conductivity and the heat capacity to be optimized, and iteratively evaluating the forced objective functions determined at least e indicate areas of the casting model, with the aid Abschreckschichten and cooling channels can be added, or insulation is added to effect an improved cycle time and / or casting quality.
