Abstract: A method and a system for casting using simulation of casting process. The system includes at least a database (130) which is relational type and contains a set of tables and relations linking them, a receiving module (110) of orders and a cast designs searching module (120) connected to the database (130) and the receiving module (110). The cast designs searching module (120) is used for determining initial searching criteria and for searching in the database (130) using the initial searching criteria in order to get a list of designs, from which every design constitutes information set defining cast production technology by means of thermo-kinetic and process engineering parameters, and best meets the searching criteria. Basing on the list of designs, an analytic module (140) of cast designs looks for a cast that meets best the initial searching criteria and further search criteria related to cast features and conforms to a manufacturer order.
