There the moulding processes of foundry have been studied. The purpose is to rise the efficiency of moulding processes according to the mould quality criterion and according to the casting quality criterion on the development basis and on the improvement basis of modern simulation methods of optimization and of control with the computer application. The mathematical simulation package for the control of sand preparation according to the quality criteria of sands, the control method of sand preparation process under the soft production system conditions, the mathematical simulator of formation of size accuracy of castings have been developed. The practical results: the rational schemes and the control methods of processes, the new designs and the new sand composition for the mould making and for the core making with the vacuum application, the determination method of gas permeability of dispersed materials, the expert system of quality diagnostics. The study results have been introduced for the sand preparation controlAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
