To achieve a sound casting of at least acceptable quality many production process parameters must be concerned. One of the most important is a casting design with the particular focus on the gating system. The better the gating system the better casting quality and this is a well-known statement. But in many cases it is very difficult and sometimes even impossible to design and make the gating system according to all theoretical and practical rules. So the issue of the gating system optimization is still interesting both from the scientific and practical point of view. In the paper the authors approach for the problem of gating system optimization was presented. The experimental casting was equipped with the typical gating system and with the optimized gating system based on professor John Campbell‘s considerations and theories. Then a computer modeling was performed, the research stand was created and the real mold pouring process was captured by high speed camera. All results were analyzed and compared and some preliminary conclusions were formulated.Keywords: Cast iron, gating system, mold pouring modelling, sound casting, pouring process
