The naturally pressurized gating system appears to be an appropriate solution for reoxidation reduction, but this type of gating system can result in supercritical melt velocity. The paper is focused on the determination of the unconventional elements effect in the gating system on the melt velocity and melt flow and their influence on the mechanical properties and microstructure. In experimental works was observed the influence of dimensioned gate, foam filters with 10 and 30 ppi density, trident gate and combination of trident gate and vortex element. Melt velocity was observed by simulation software and via velocity measurement by contact method in the mold during casting. Melt flow was analyzed by simulation software and water model experiment. Experimental casts have been made for the purpose of evaluating mechanical properties and microstructure determination. The best results were achieved by 30 ppi foam filter.
