While the development process from the idea to production led in the past from the drawing board via model construction, test casting and various adjustments to the finished product, computer-aided design (CAD), simulation, computer-aided manufacturing (CAM) and prototyping are used today.
In brief, we speak of computer-aided engineering (CAE). With regard to model construction and also, specifically, the development and design of casting systems, this has certainly been the case for some years now. We are all familiar with the advantages and possibilities that simulation methods offer in this context.
However, the simulation of core production must still be considered to be relatively new. But do we need this type of simulation? Surely, nobody knows more about their core business, i.e. their core production, than experienced casters themselves.
Nevertheless, we must ask ourselves – is this true? Do we really know what happens and whether we have designed the most optimum setup?
You could almost say that this sheds light on one of the last dark areas of our casting processes, and that this helps us to master our “core business” even better.
Two key simulation steps are distinguished in core shooting simulation. The first is the simulation of the filling process of the core box, i.e. the actual shooting of the core. The second is possible or necessary gassing, i.e. a through-flow of gas through a cavity of a core box with any type of filling.
