This work deals with the problem of casting production from high-aluminum cast iron Al22D. This cast iron is characterized by unique combination of properties [1-3]: high heat-resistance in corrosive gases medium especially containing sulfurous gases; relatively low density in comparison with gray iron and satisfactory mechanical properties. In addition, castings made from high aluminum cast iron Al22D are required in many areas of mechanical engineering. However, obtaining high-quality products from this cast iron is a particular problem due to its low-casting properties, especially its high tendency to gas saturation, oxidization and forming scabs, shrinkage and gas-shrinkage defects. Therefore, the aim of this work is the study of the castings feeding parameters. In addition, the technology of "exhaust manifold" casting of internal combustion engine designed to work in forced mode was developed on the basis of the obtained results.
