Industry groups such as lost foam casting equipment, casting production enterprises, equipment manufacturing enterprises, universities, and scientific research institutions have strengthened cooperation in the application theory of casting technology, equipment design and manufacturing theory, and conducted research on the theory and application of equipment guarantee technology, increased research and development efforts, and studied and improved the functions, structures, and application effects of existing equipment. Automatic control function has been added to the pre foaming machine and molding machine. The selection and improvement of the vibration table should be combined with the structural characteristics and production organization form of the casting, to make the vibration compaction effect of dry sand more coordinated and uniform. In addition, strengthen research on the cooling principle of sand coolers, improve cooling effectiveness and efficiency, and reduce energy consumption and noise. Improve old sand screening equipment, improve screening efficiency and effectiveness, reduce energy consumption and noise; Increase the research and development efforts of exhaust gas treatment devices for lost foam casting, improve on the existing research results, and quickly put them into production and application in casting enterprises, gradually incorporating necessary environmental protection equipment into lost foam casting production enterprises.
