To improve the internal casting, external quality and reduce the machining allowance,and further extend the application of greenprocess with air impact, high pressure, injection pressure, extrusion molding and other high degree of mechanization, automation, high density is the main developing direction for small castings production in the future . It is the key point to promote the application of green sand molding process to modify bentonite by nanotechnology,or improve the quality of bentonite by adding adhesive technology in it.
Facing the situation of severe competition in international market after entering the WTO, industry of sand casting machine needs to combine production,research and innovation under the necessity of the situation in our country.If the industry of sand casting machine make great efforts to develop new productions with advanced,efficient,low consumption, practical benefits and independent intellectual property rights, this industry would break a small investment, quick shortcut to change most sand casting enterprise with backward technology.
It is necessary to develop the precision forming technology so that we can vigorously develop the visualization of sand casting technology, and promote numerical simulation technology of sandbased on CAE towards integrated,virtual,intelligent and practical technology. To further improve the modernization level of sand casting,the technology of CAD/CAM/CAE/RPM,reverse engineering, concurrent engineering, remote design and manufacture,intelligent and on-line operation should be in full swing.
