The production process of thin-walled iron castings with complex shapes, characterized by high quality while maintaining the required properties, involves many steps. One of them is the appropriate selection of the technology for molding and core sands, taking into account strict environmental requirements. The need to meet high environmental standards is currently the dominant factor in the development of molding sands technologies. It is even being done at the expense of reducing the technological properties of the materials. As part of the development of molding compounds for thin-walled castings, two compounds with organic binders and two compounds with inorganic binders were tested. Tests were carried out on the tensile and bending strength, density, permeability, and friability of the compounds. Their thermophysical behavior was tested via the hot distortion parameter. The tests carried out on the molding sands showed that all the proposed mixtures have the appropriate properties for the production of thin-walled castings.
