Core shooting apparatus and method for controlling core shooting apparatus

A core shooting machine for producing cores by a process of shooting a core sand mixture into at least one cavity in a core box that is associated with said core shooting machine, said core shooting machine comprising:

• a source of compressed air at an adjustable initial machine pressure, said adjustable initial machine pressure, being an adjustable process condition of the process, and
• a shooting head fluidically coupled to said source of compressed air by at least one conduit that includes an electronically controlled shot valve, said shooting head being configured for containing an amount of said core sand mixture, resulting in a filling degree of the shooting head, said filling degree being an adjustable process condition of the process, and
• a computing device associated with said core shooting machine, said computing device being configured to be informed of several process conditions, including said adjustable process conditions and to perform a simulation of said process to determine an improved or optimal value for one or more adjustable process conditions based on the result of a performed simulation, said simulation using a model of said process and comprising solving a system of coupled equations to determine the transient fluid flow of the core sand mixture and air, and
• wherein, said computing device adjusts one or more of said adjustable process conditions in accordance with the determined improved or optimal value.
