The results of studies of the cores production by blowing methods with utilising the modified experimental shooting machine SR-3D, are provided in the hereby paper. The core sands from the Cordis technology were applied in the presented investigations. The influence of the number and distribution of vents on the shaped core box filling, filmed by a digital camera, was determined. Investigations were performed for the shooting pressures of 0.4, 0.5 and 0.6 MPa and for three surfaces of the shooting hole, at various numbers and distribution ways of vents in the experimental core box. The selected results of the model investigations were compared with the results of simulations performed previously in the PROCAST programme. The intensity of the core sand outflow from the shooting chamber into the core box of the experimental shooting machine was measured. Technological effects were assessed on the basis of the core sand apparent density in individual parts of the core, in dependence on the character of the pressure increase in the shooting chamber and the pressure value obtained in the core box.
